I had a misfire and my CEL came on had it read and it said cylinder 4 was misfiring and that there was a misfire in the first 1,000 RPM's. I replaced the COP and plug and now I'm getting terrible MPG. I tried to reset the PCM by removing the Neg. battery connection and it seemed to work for 4 days now my MPG has gone bad again. It seems to run smooth/good.
View 1 RepliesI've got an issue on my Escape, and I'm at a dead end. '01 XLT V6 150K miles.
About a week ago, driving to work, it started stuttering or misfiring while accelerating up inclines. Cruising and idle were smooth with no issues. I found that if I let off the gas as it was stuttering, it would stop, and then I'd give it gas again, and it would be fine. It was pretty intermittent.
Opened the hood and the large vacuum hose that goes from the top of the intake down to the PCV, has an L boot that connects it to the intake. That boot was collapsed down on itself while the motor was running. It went back to normal when I shut it down. I felt the boot and it was very thin and worn out, so I replace the whole two piece hose, along with the PCV valve. The old PCV came out and was rattling, so I believe it was ok, but I installed a new one anyway.
Drove it after that and it still had the stutter. It was now also doing it just barely at idle. I'd hear the motor miss, and it would really start when I would give it gas. I thought it was still a vacuum issue, and that there were probably other bad hoses. I found two. There's a small hard plastic line that comes off the air intake hose from a T, and those lines go to the camshaft covers. The hard lines go to rubber boots on the cover, and the one in the back was in two pieces. Replaced it. No change.
The other line is a small rubber line that comes off a round component, (I still haven't found out exactly what this part is called), that is bolted to the drivers side shock mount, and has a couple soft lines coming off of it. One of the lines goes over the top of the motor and ties into a T right where that large PCV hose goes into the intake. The part is circled in red, and the arrows point to the hose in the attached pic.
I have a 2002 Ford Escape, 6cyl FWD... 110,000 miles.
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.
My escape struggles to reach 30 mph.. throttle position sensor code when scanned.Replaced the sensor but still barely any power check engine light hasnt come back on.
View 9 RepliesI'm replacing the ignition lock cylinder on my 03 Escape. The factory cylinder has the little black "wings" that nestle around the key when inserted:
The locksmith says the replacement cylinder needs to have those same wings for him to be change it. Is this correct? The auto part stores have the regular cylinder (with no wings) readily available, but the one with wings is a special-order item and I need this sooner rather than later.
Plus, the wingless one includes keys while the other appears to have none.
I have a 2001 ford escape v6 the engine light is on and when advance pulled a code it came back egr valve is sticking and #2 is not firing.. I have a 2002 v6 parts car that I ran hot I took both parts off and put on my 01 buts its still running the same..
View 7 RepliesI 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.
View 2 RepliesBrought home tonight a 2001 Ford Escape 3.0L 24 Valve V6. Bought it from a mechanic who's customer didn't want to put any more money into it. Has 185000 miles on it and it throwing the P0303 & P0171 codes. Cylinder 3 miss and Lean condition bank1.
Mechanic thinks it is a valve seat in the cylinder head next to the fire wall. Before I start replacing the cylinder heads with new remanufactured heads I plan on doing a compression test and leak down test.?
So I am changing my transmission fluid tomorrow and was wondering a few things.
1. I noticed some people pull off the transmission hose to the inlet and keep draining that until its clear. For a drain and fill do you do it like that or just pull the plug and refill?
2. When youre filling it back up you just measure how much you taken out and then fill the rest by the dipstick? Anything else i should know?
3. Since I havent changed my transmission fluid in 60,000 miles. I wanted to do a drain and fill. I was thinking I needed to drain and fill it 3 time to catch up to maintenance. How often would you do it to get it clear? Drain and fill then drive it for a week then drain and fill? Or do it all in one day?
Less than 2 months ago I bought a 2002 Ford Escape with 165000 miles. It has been nothing but trouble. 3 days after I bought it, it misfired for the first time. It stopped on its own and I let it go because that day the brakes also went out.
It seemed fine for a few weeks and then the check engine light came on it was a code for the 02 censor. Some fuel injector cleaner did the trick.
A week later it started misfiring again. I couldn't drive it to get the code checked so I replaced the coil pack on the cylinder that misfired last time. I drove it that night it wasn't misfiring but it would barely get to 50 mph. When I tried to start it again it made a loud squealing when I press the gas. I still don't have a CEL.
Changed the spark plugs now I have misfire in cylinders 3 and 6. Do I change the spark plug wires or the coil pack?
View 5 RepliesHad a misfire in cylinder 1 so I put new plugs and wires. Still misfired. Changed fuel injector. Still misfired. Changed ignition coil and misfire on cylinder 1 is gone now cylinder 2 and 3 are misfiring. I double checked wires and they are properly installed.
View 11 RepliesTrucks throwing codes for cylinder 3 and 8 misfire. I pulled the plugs and both were covered in oil and cylinder 8s electrode was literally gone. so I replaced the plugs and within 5 miles it was missing again. so I replaced all plugs, all wires and coil packs. cylinder 8 plug had fouled out. Its a 4.6l 99. I have a mild exhaust leak where the manifold connects to the downpipe. but not bad enough I feel it should matter. it runs rough until about 3k rpm and then it kinda straightens out.
View 14 RepliesI've got a 2000 Ford Ranger, manual 4 cyl. When cold, she's been stalling out. It happens very reliably when I come to a stop and put it in neutral (or put the clutch in). Only when she gets warmed up does it stop. Check engine light has been on (for a long time) saying the TPS sensor is out and the 4 cyl. is misfiring. I replaced the TPS sensor and it had no effect on the problem. A friend recommended changing the oxygen sensor.
View 5 RepliesHad a miss in the #5 cylinder on a 2005 F-150 5.4 Triton. Had it hooked up to see which code was given and the tech said that #5 was the culprit. Taking no chances, I purchased a new plug and coil pack. I installed them and it ran great until I got up to around 70mph and then it started dong the same thing it was doing earlier. I took it back to the place that checked the codes and it came back as the #5 cylinder misfiring again. I am not sure how this is possible after replacing the plug and coil pack. Is there some way that the plug that fires just ahead of #5 is fouled out and causing the #5 cylinder to get too much fuel transferred to that cylinder? Or is there a possible short somewhere causing that cylinder to misfire and ruin the coil pack? I am stumped on this for the moment anyway.
View 8 RepliesI got this 98 Ranger 2.5 that I've done a tune-up on less than 30,000 miles ago. I changed plugs, wires, and both coil packs. Timing belt, thermostat, fuel pump, fuel injectors are all recently changed too within a year or two. Fuel filter and air filter I change every 30,000 miles. The truck runs as great as a 4 Cylinder will run. It's at 344,000 miles but the engine was changed once so it probably has over 100,000 miles on it. There is just a slight miss you can hear through the tailpipe but it's not severe enough to be picked up by the Check Engine Light. In fact, even when the coils were totally gone it never put up the Check Engine Light. I can tell when a coil pack is going out on this because it's done it several times so I usually just change them with the tune-up. It's only a slight miss some people may not even notice it. I was just wondering is there any way to track down where the miss is? I tried looking under the hood in the pitch black and there's no plug arcing.
View 1 Replies2004 5.4L ... Codes indicate a firing issue on #4 cylinder, figure it's the coil pack. They bought truck used a few years ago and plugs have not been changed since they have owned it. I was going to change plugs while I was under the hood. While checking threads on this engine I picked up on plugs being a major job unless you know the tricks. So what tricks do y'all have up your sleeve to keep from breaking plugs?
View 14 RepliesBackground: No A/C. Identified Clutch had completely failed. I replaced the clutch.
Status: I turned on the A/C and I saw the clutch come on...it was on for maybe 60s. During that time, the vents started to get cold! After 60s it never came on again.
Troubleshooting: I have refrigeration gauges but not much idea how to read the result. I hooked them up and noted about 350psi for the HP side, and about 100psi for the LP side. I think this tells me I should have enough charge in the system to cycle the compressor.
At this point I don't want to start random troubleshooting as I don't want to touch the refrigerant loop more than necessary. A few questions:
1) The HPCO switch, I was reading that it's mounted on a Shrader valve. Is this the case? I'd like to remove it and test at which point it switches. I have not tried bypassing it.
2) Do our vehicles have a temperature sensor near the evaporator? If so, whereabouts is it located?
My 2006 Escape Hybrid with <3500 miles on it had the ABS and 4X4 lights light today when I am 60 miles from home. I had this happen a few years ago, and I replaced a cracked tone ring, driving it to the dealer, who was only 5 miles away. My question is, is it safe to drive home and take it to my dealer who is 60 miles away, or should I have it towed?
The vehicle runs, in fact, the ABS and 4x4 light went out - in fact, I think I saw an indicator message that said 4x4 restored, but I am not sure, it appeared and then was replaced by X miles to empty. I would prefer to go home and take it to the dealer I purchased it from, but I don't want to drive in a car where the brakes may not work. I've read differing accounts on the internet and I can't figure if this is a "service soon" meaning I can make the trip home, or if it will strand me or worse if the brakes will fail on the trip home.
I just bought a 2010 Escape XLT 4 cyl. The mpg is showing to be 16.7, which is really low compared to what it's supposed to be. I bought it off of a car lot and it had been discounted so I'm guessing it was sitting there for a while before it was sold. Do you think that would cause the mpg to be low? I've driven it on the highway and around town. I've had it for 2 days, but it's freaking me out thinking that there is something wrong with it.
View 4 RepliesI have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...
