I am having some ( Bad Luck ) with my 02 escape I been getting random misfire codes started checking over o2 sensors first, replaced one on bank 1 downstream, I have screenshots to look over along with codes....

About a month ago I started seeing a misfire, which of course usually is a COP issue. I should buy stock in whoever makes those. Anyway, the code according to parts store monkey was cylinder 2 misfire, so I replaced the COP. That made no difference. I also replaced the upper intake gaskets and the PCV valve while I was in there.
So I started monitoring when it would happen, and of course got the actual code rather than taking the word of the monkey at the parts store. The code is P0352 Primary / Secondary circuit malfunction.
So after some research I find it could be the harness, it could be the PCM. The question I have is this misfire seems to only be when the motor is started after it's hot. What I mean is I can drive to work 10 miles, no problem. I can drive to Orlando 100 miles away - no problem as long as I don't stop on the way. The only time the misfire happens is when I start the motor when it's hot. So if I drive 10 miles to the store, then drive home before the motor cools completely I'll be coming home on 5 cylinders. If I wait 2 hours between stop and start I never have a misfire.
Does that jive with a true electrical problem? I'm no expert, but I don't understand why driving for 100 miles is fine, but 10 miles, stop start and 10 more is an electrical problem.
I have a very Big problem with my Ford Escape 2002 I have this problems code: P0305 accuses Cylinder #5 P0306 accuses Cylinder #6.
I already change the gasket i buy the felpro Kit, and i Also replace all the sparks and spark plug boots, I clean the air sensors and i also replace the EGR, i try to switch cables, and all is the same the car start buy when i accelerate it just go off, i don't know what can i do next, somebody told me to change the fuel injector, i take the pressure in both spark holes the number 4 was 150 and the 5 and 6 was 120, No leaks oil. My car is a Ford Escape 2002, XLT 3.0 4x4
I am having a lot of issues with my 2002 ford escape, a while if I drive the truck acts normal, but after driving it starts missing when beginning to accelerate at a dead stop check engine light starts flashing pulled codes coming up with #4 cylinder misfire and #5 cylinder misfire detected, also a catalyst system below threshold bank 2, I have had the vacuum lines repaired and still no changes and went through and changed my grade of fuel from regular unleaded fuel to premium fuel, actually went worse with using premium fuel. I was thinking of replacing all three coil on the front of the motor, putting new plugs in it and seeing what that does.

Problem: 2 possibly related
1) If warm up (get to about 190+ degrees) and then cut off engine. Does not start. If I wait about 30 secs and play the gas pedal, then I can get it to start with high revs and after about 15 secs runs normally. Or, I can disconnect the air intake and it'll start fine. But if you stop and try to start again, no joy unless playing with gas pedal.
2) After driving about 20-25 mins, it seems to randomly stall-out while going about 40 mph. When it stalls out, it will restart again after about 30 secs.
Note: Neither of the above throw any codes.
Here's my problem chart after mining the other posts:
Thing to replace/do //// No Code /// Stall while driving /// Won't restart when hot
Fuel Pump //// Yes /// Yes /// Doubt it
Fuel Filter //// Yes /// Yes /// Don't think so
CKP Sensor //// Yes /// Yes /// Yes
CMP Sensor //// Unlikely /// ? /// Possibly
ECT //// Maybe? /// Yes (if too hot) /// Yes
IAC Valve //// Unlikely /// Yes /// No
Thermostat //// Yes /// Yes (if too hot) /// Yes
MAF sensor //// Unlikely /// No /// Yes
What I've done:
- Well, I started looking at the vacuum lines and they were crumbling so I replaced all those (to EGR and all that).
- There is a mystery line that appears to come up from the canister and go to nothing--is this some kind of atmospheric vent?
- My cheap scan tool also shows engine temps getting up to 216 degrees if I make it work (idle high at 2000+ rpm), so I'm suspicious of the cooling system and thinking maybe the ECU is shutting down to avoid overheating.
I'm going to start with flushing the coolant and replacing the ECT and thermostat while doing so. This is relatively inexpensive and ECT can do weird things. The restart problem is consistent, so I'll know if I fixed that right away.
I have a 2009 Escape, 2.5l engine and manual 5 speed transmission, 205,000 miles. It has has an intermittent miss that has been getting gradually worse over the past 3 months or so. I've been seriously futzing with it for the past 2 months, so far no luck. Definitely worse when it's cold. Not noticeable at all in gears 1-3 (even when cold), noticeable in 4th, mostly between ~2000-2500 RPM, and pretty bad when cold in 5th in the same RPM range, still noticeable when warm. No service engine light until today (#1 misfire).
If I let the vehicle idle for 10 minutes or so, the miss is much less noticeable. Replaced the plugs, absolutely no difference. Bought one COP and cycled through all cylinders, no difference. Finally broke down and took it to the Ford dealership where I bought it new and had them do a power balance test, which isolated it to cylinder #1. Swapped the #1 and #2 injectors and took it back to Ford, still showing cylinder #1. Did a compression test, #1 and #2 both around 165lbs, #3 and #4 both around 185lbs.
I'm a electrical engineer, so I spent some quality time with an oscilloscope to compare the drive waveforms of the #1 and #2 cylinder COP and injector...both COP and injector drive waveforms look identical when comparing to #2 cyl. Tried heating the PCM, made no difference (engine was cold, PCM was hot).
So it finally DID throw a code today, cylinder 1 misfire. I'm thinking I can almost hear a miss at idle now. And listening to the valvetrain at idle, there is unmistakably more valve noise coming from the #1 intake area than the other cylinders, but not terrible.
What to look for. 2001 escape 3.0 starts and runs but it has a miss and no codes came up yet . the engine will rev up but it really takes time to idle down . don't matter if its cold or hot it just don't want to drop to idle as fast as it should.
View 4 RepliesI have a 2001 Escape 3.0 l 6 cyl. She stalls or almost stalls every time I fuel up. I found if I turn key but not to start, it only severely sputters and usually doesn't stall. Replaced EVAP canister (and all but dust separator inside), fuel pump, EGR valve, pcv tube, iac, upper gaskets, valve cover gaskets, seals, spark plugs, fuel/air filter, evap purge valve, fuel filler cap, ftp sensor, all ignition coils, checked for clogged fuel filler neck, fuel/vent hoses from/to evap canister...nothing worked.
There is a hose I cant get to that ends unattached just past fuel tank and near fuel vapor(?) "tee" under car. Seems to come from fuel tank. What is it? Just an overflow vapor hose? Should it be attached to something? Anyway, I suspect fuel vent hose or valve on top of fuel tank since my options are limited now. Have it running great (except this issue) with 260,000 miles so really don't want to spend mucho $$. No codes thrown.
I have a 2005 F-150 W/ 5.4 triton, and am having multiple codes. They are:
P0172- System to rich(Bank 1),
P0174- System to lean(Bank 2),
P0300- Random misfire,
P0303- Cylinder # 3 misfire detected,
P0304- Cylinder #4 msfire detected.
My g/f's 2004 Ford Escape (3.0L V6 AWD 112,000mi) is acting up. After a full day of sitting, with the second half of it raining steadily, she was driving her Escape and it was acting funny (miss-firing, she said). The engine light came on and soon began blinking. She got to my house shortly after it started this. We left it and I drove for the day. Later that night, I drove it and it seemed fine. The engine light was on, but not flashing anymore.
The next day I took it my friend that was a Saturn mechanic and now working at a KIA dealership (same owner as the former Saturn and current Buick/GMC and Chevy Dealer). It ran fine for me. So he tries to scan it, his Mac Tools scanner won't read it. The KIA scanner wouldn't read it. I drove it the Ford dealer up the road. They said they couldn't get to it until after lunch, I just want the codes read. They re-iterated, and I told them to pound salt and went to an independent shop where I know a guy. They read it right away for me. "Mis-fire on start-up" & "Cylinder 4 Mis-fire." were the two codes stored. He cleared them.
She got the tune up basics (plugs, wires, air filter, etc) and did the complete tune-up herself yesterday. (I was impressed). She put 94 in the tank and some fuel system cleaner in it as well. She said there's been no change and today I finally saw what it was doing. Sometimes during idling at a stop light, the RPMs will drop to almost zero, the lights dim but so far it has not stalled. It'll do this for several seconds, then correct itself and idle normally.
Currently, the engine light has not come back on. She's thinking coil pack (each cylinder has a coil on these engines) on #4. She wants to switch it out with #1 and see if the problem follows. I think that might uncover the cause, or it could be the battery. It's the original, never been replaced and has a lot of miles on it, but it survived this past winter, without trouble. In my experience, most batteries crap out due to age in the fall when the cold snaps start.
My wife has a 2004 escape v6 (3.0L). The valve cover seal was leaking so I decided, why not change the plugs since I'm already going to have the intake manifold off.
I got down there, replaced the seal (just the front side, didn't want to disassemble something that wasn't broke) and then replaced all 6 plugs and boots (with springs). Fired it up and everything seemed fine. She went to drive to work and the CEL started to flash. I read the code and there were 4 (Don't remember exactly what they were), but it was a combination of things resulting from a misfire in cylinder 4. Since it was one of the front ones. I just pulled the plugged and replaced it hoping I had gotten a dud from the factory. Nope, still doing it.
I didn't take off the fuel lines, just the air intake on the top. I did not change the coils, but everything was running fine before I changed plugs so logic would dictate it is something I did. Only seems to misfire at higher speeds. Also, her battery light randomly comes on, but the battery and alternator test good. This has been happening a while.
I'm needing cold engine misfire. 2001 escape 3.0 engine 190300 miles on it. I changed the plugs, cleaned the fuel injectors, new air filter, new fuel filter, cleaned the pcv valve and new ideal control valve. When the engine is cold it starts right up but wont idle right and misfires sputters some to but run the rpm's up and it smooths out. drop to idle and it misses. Now when the engine gets to operating temp it seems to run fine. What am I overlooking to find the problem?
View 5 Replies99 F-250 SD 6.8 had an issue with it while moving from Del to Phx, Az. Found collapsed air cleaner element. It looked like someone stepped on it. I replaced it as well as the MAF. This fixed the issue. This was 350 miles into the trip. The truck seemed to be down on power as it didn't want to pull my trailer up any type of grade except with OD off. Around 2K miles into the trip in developed a random misfire with no codes. I am at my final destination and the misfire is worse. I am not showing any codes at all or pending either. It is a bit toasty outside to be out there diagnosing issues, and I won't start changing parts randomly either. I have a NGS scan tool with the proper cards.
View 5 RepliesNew plug on right, lower bank 2 plug on left
Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.
Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.
Have a 2006 ford escape, at idle the engine will run around 1000 rpm's and then regularly dip down 500 rpm's. Through the intake i can here a distinct "thwap" when the RPM's dip.
Only codes are
P0113 and P2196
Problems accelerating sometimes, Took it too a shop they said bad exhaust valve on the backside of the engine either 1-2-3. They said needed engine work, but said they didn't know where the bad valve was so i don't even know how the made the determination. Vac gauge at idle also indicates bad valve.
However, when i give it even the smallest amount of gas possible the engine smooths out and vac gauge reads totally normal and steady.
I got a 2001 Escape XLT (V6) a couple of months ago. Its in great condition, only 82k miles on it too. It had the notorious door handle issues which I have had fixed. It also had the wet weather stuttering problem, which I had fixed by having all 6 spark plugs replaced (Motorcraft OEM plugs), the back 3 coils replaced, upper intake gaskets replaced, Valve cover gasket replaced, PCV valve replaced (motorcraft).
It runs great when its warm, the problem I am having is when its cold outside and the engine is cold, it starts up fine but idles like crap and if its really cold outside, it starts and dies 3 or 4 times before it can even get to the crappy, stuttering idle. I have to intermittently feed it gas to keep the cold idle going long enough (3 or 4 minutes) before I can drive it. Once the engine is warm it drives like a champ. The only warm engine issue, is occasionally after driving it and putting it in park, the engine will rev up to 2000, 3000+ rpms, and just keep going up until I shut the engine off.
The codes read P0171 and P0174, which are lean on bank 1 and bank 2. It had also thrown a misfire on cyl 6 but once I cleared that it hasn't come back, just the lean codes are still present.
From what Ive been reading, this can be a number of issues, ranging from the IAC valve, EGR valve, MAF or the lower intake gaskets. I'm very much a rookie when it comes to car mechanics, but I think I can handle changing the IAC, EGR and MAF since they are all on top of the engine. However I don't know if I could handle the lower intake gaskets. Ironically, the gaskets are the cheapest part, but the most labor if I paid someone else to do it.
If I replace the EGR, do I also need to replace the EGR Modulator as well? Looking for brand names that are best bang for the buck when it comes to these other parts I have mentioned?
A couple of weeks ago I got a check engine light. Pulling the codes I saw that it was a p0304 and sometimes a p0316. The first time this happened I check the spark plug cables and one was loose (cycylinder 4). Then last week my fuel pump died. since then I have gotten the two codes on a somewhat continous basis. I replaced the plugs (needed to anyway) and the problem did not go away.
The odd thing is that the check engine light does not come on at idle. IT only comes on after the motor is at a higher rev. The replaced plugs looked pretty normal, but the cylinder 4 plug had some carbon deposits. I am currently running injector cleaner in the gas. I may go ahead and replace the plug wires since the current ones are high mileage and it is not an expensive fix.
I am running into some issues with my 2011 Escape 2.5L. I am pulling a total of 7 codes. Two codes keep repeating, which those are P0455 and P0457. And I am also getting a C1963. Accompanying the engine codes, my HUD is displaying "Check Fuel Inlet" when I first turn the vehicle on.
View 10 RepliesTrying to troubleshoot my 2001 Elantra (173k). I'm having intermittent trouble codes being set and I'm wondering if they may be related:
P0302
P0303
P0446
The cylinder 2 and 3 misfires are relatively recent. Plugs and wires are visually ok (and not that old). I swapped plugs 1 and 4 with 2 and 3 to see if the plugs are bad. It took 3-4 days, but the P0303 set again (and it's very intermittent - car will noticeably lose power for a few seconds, code set, then run fine for several days). I also sprayed carb cleaner on the intake manifold gasket with no change in engine idle, so the gasket appears to be intact.
I had read in a forum somewhere that the misfires could be related to a vacuum leak, which could also be setting the P0446 code. I removed the charcoal canister and inspected the lines - visually ok.
I bench-tested the canister control valve and it did operate, though I noticed some charcoal blocking the valve so it would not close all the way when energized. I used compressed air to blow the debris out of the valve and it appears to close properly now.
I went to hmaservice.com and noticed there are no instructions for the P0446 DTC. I've been using a Haynes manual instead. For quite some time now when refueling, the fuel nozzle shuts off every few seconds (I have to slowly put the fuel in to avoid).
Some questions:
- Can these codes be related?
- Based on my symptoms, should I replace the canister control valve? What about the charcoal canister and the charcoal air filter - should those be replaced as well?
- What else should I check?
Yesterday, i changed the spark plugs, spark plug wires, mass air flow sensor, air filter and replaced the in and out take coolant lines in the throttle body.
Before yesterday, i got random misfire codes that would clear and return, i have no a/c, i believe the thermostat needs replacing as the van runs hot after a while of running and quickly when idling and the upper radiator hose is hot. The van's idle is rough to the point that some one else turned up the idle so it would stop stalling so frequently, especially in reverse. it stalls very very rarely now.
then a few days a go i got a knock sensor code that clears itself and then returns.
A friend changed the distributor cap, and noticed some melting and corrosion, hence the spark plug and wire change. this friend also pulled the wiring harness for the front 3 injectors while it was running. the one on the far right created no audible engine change (also this spark plug was immaculate compared to the others), so he said it is bad (or is my friend a moron?)i had also noticed a coolant hose that would spray coolant when really hot.
So yesterday i tackled the above. In the process of doing this i had to rip the other coolant hose to remove throttle body, i replaced these with a self cut piece of 1/2 heater hose. after removing throttle body, i realized i needed a gasket. so got one of those.
a few notes:i used antisieze lube and dielectric lube on spark plugs, thread and ceramic respectively. the mass air flow sensor is used.i cleaned the throttle valve with brake cleaner (non chlorinated) because it was nasty! i did not remove the cables attached to throttle body, just moved it out of the way while working.i hand tightened everything.there were 2 skinny hoses i disconnected, one with a metal tip that went in to the large rubber air intake hose, and one that ran into the throttle body (this hose ripped like a 1/4 inch off it seemed long enough, so i did not replace). i disconnected the large air intake hose at 3 spots with pipe clamps.i disconnected 3 wiring harnesses 2 at throttle body and 1 at mass air flow sensor
Now, it seems the van is running smoother while getting gas, but rougher when idling. What did i miss? what would be causing a rougher idle? I am now at work, i will not be home till around 9 cst. So I cannot check anything.the van did throw another code, but i have not checked it yet.
My 07 3.3 SF is throwing P0154 and P0300 codes. Autozone said the P0154 is Bank 2 pre-cat O2 sensor. But exactly which one? The P0300 is random misfire. Could they be related?
