Ford - Explorer :: 1998 - Running Rough - Cut Out - Got PO453 Code - Changed Gas Cap But Nothing?
Apr 10, 2013
I have a 98 sport 4.0 i bought awhile back and its been running rough.. When driving it seems to cut out.. I had it scanned and it has code PO453 which is pressure sensor.. I was told they replaced the fuel pump when i got it.. After driving and i get out i can smell gas on the drivers side.. I replaced the gas cap but no change.. I was just wondering about this code and what i should start with first..

1997..FordF150 4.6L 4x4 Manual transmission ~~
To start ... truck seem to be having misfire issues one day...first thought was gas tank was low and running out of gas with no warning from low fuel light. Made it to station got gas no more trouble. Week or so later climbed in truck that morning went to start it and felt like it was running off 4 cylinders, shaking, misfire and engine light flickering constantly.. eventually died left it off took the Harley to work...
Later that evening after I got home put scanner on it got a code PO453 "Evaporation Emissions Control System Pressure Sensor High Input".. Looked it up.. found the location to be on top fuel tank...first thought great gotta drop tank to replace sensor... after the scan reset sensor. Next mourning started truck ran great ..no engine light... took it for a spin no problems parked it. Next mourning going to work started it same problem...Shake Rattle and Roll...
Friend told me to unhook ground cable to reset computer... did it..left it for couple hours..hooked it back up..started fine..no engine light running great drove it 3 to 4 miles no problems. Took it to car wash cleaned it started again drove home parked it. Next mourning same thing shaky shaky...
Took to local shop to have it checked out (drove it there ran great with engine light on)... they seem to think sensor is OK.... Their thought P C M.. Supposedly took PCM off cleaned contacts and one of the mechanics drove truck home with no problems...next mourning same issue shaky shaky.... New PCM right direction ?

I have 2007 explorer with the 4.6 V8....
Recently it started running horrible. Rough idle, drives badly, hesitation, etc. Check engine light is on, code P0171. I cannot find a vacuum leak, and i am pretty much at a loss. Before it started running poorly i replaced the thermostat, and flushed the coolant. I am assuming this is a coincidence.

so recently I purchased a 98 Chevy s10 with the check engine light on. Seemed like a good deal. Has a battery warning light constantly on and I have to turn and reset the ignition a few times each morning to get the engine to start but it ran relatively smoothly. I waited a day, then tried to reset the light by disconnecting the battery and cycling it. The light never cleared. Once my scanner came in the mail I ran it and came back with a PO453 (High pressure in EVAP) code.Looked it up, could be a variety of causes, and as I don't really have a place to tinker with it too much I started with the easy stuff. Checked gas cap, seems a bit weartherized and probably needs to be replaced. Got under the vehicle and had barely enough clearance to disconnect what I believe to be the FTP sensor .
Started the vehicle, stopped, then ran the code again, only this time it came up as a PO452 (EVAP pressure low). Reconnected the sensor, erased the codes and again the check engine light stayed on. Went to work today, code on. Got off and the check engine light was gone! Excitedly I ran the codes again when I parked at home and it still came up with PO452, but the Check Engine light is still off.

My F150 with 175,000 miles on gave me a the ol' P0305 code indicating misfiring in cylinder #5. I changed the plugs and wires using Motorcraft wires and Motorcraft AGS34FM plugs.
Now the truck idles fine, does not give a OBD code but runs rough at 2,000-2,500 rpm. Tried it out on the highway and it started "bucking" a bit. Not sure what to try next.

My 2002 Ford Explorer 4L V6 is running rough I found out why I just don't know what the piece is called because I need a replacement. Mine fell off and fell down the engine and melted quite a bit. Also the part number on my piece doesn't work anywhere, that I have typed it in. Mine has a Ford part number of 1L2U-9F764-AC. Also need to know the proper Ford number. I have a picture I found online with an arrow pointing to the piece I need.

My explorer has been running a little rough, particularly at idle. When I take off from a rough idle, it'll run rough until I hit 25-30mph. I ran by O'Reilly's hoping to pick up a pack of spark plugs and be done with it, ended up leaving with a new MAF sensor. It ran better for about 10 miles (I'm a delivery driver, so I did a lot of stop and go immediately), before it ran even worse than it did before, but at least my CEL finally came on. Took it back to O'Reilly's and they read a MAF sensor code and a catalytic system code (didn't ask for the codes, and now realize that was a mistake).
So today I took it to a muffler shop to have the catalytic system diagnosed. They looked at it for 10 minutes and told me they didn't think it was the converter. They said it seemed more like the EGR valve or solenoid, or the IAC. He scanned the codes again and got multiple "running lean" codes (0171, 0174, etc). The guy said I didn't have a vacuum leak, so I think I can rule that out. Unfortunately, the truck idled fine the whole time so he didn't feel comfortable giving me a definitive answer. He told to to leave the EGR valve hose unplugged for a few days and see if anything changes. I'm thinking about running a bottle of fuel cleaner through it or taking off the IAC and/or EGR and cleaning them myself.

ok, 3 times now I've been extremely close to being hit head on by oncoming traffic due to a seemingly uncurable stalling problem. It idles rough sometimes, and other times it seems fine. BUT when sitting at a light, waiting to turn left after the oncoming traffic has a quick opening, I start to go, I get halfway across the intersection and then without warning, it dies completely. Now its too late to stop and back up- and the cars are flying head on towards you locking up they're brakes. One time I would have been killed by the 18 wheeler that was coming if I hadn't gotten it started and moving again just in time.
I replaced the IAC, the plugs, filters and wires, and the EGR valve. I checked everywhere for intake leaks and found nothing. Changed the O2 sensors since they had plenty of mileage on em. It idles like crap still, even after 30+ tanks of every kind of injector cleaner they make. We used the snap on scanner tool to monitor things and it never acted up then. The TPS seems to move smoothly, and fuel pressure was checked and found to be around 25-30 psi. Don't know if that's normal. The intake air temp was reading a constant 120 degrees F. I also checked the fuel cap to make sure it was closing completely. The dealer checked the TB for excessive clearance and said it was ok.
It seems to only stall like that after driving on the highway and then stopping at the first light after that.

I have been puzzled to why my truck isn't running right. We were driving down the highway one day and*then all of the sudden it starts running really rough. I changed MAF sensor, plugs and plug wires, oil change, fuel filter and air filter. Still doing the same thing. What this could be? 2003 ford sport trac..

I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.

On my V8 02 XLT Explorer the engine is running rough like it's missing.
I think a coil may have gone bad,,found a LOT of anti-freeze down in the spark plug hole.
Have replaced the intake but now need to fix the roughness.
Is there any easy way to check each coil? Or should I be checing something else?

98 5.0 last week i was driving around for a few hours and everything was fine. Did some work in the garage for a few hours and had to run to the hardware store. Started the truck up and she ran like crap. Engine shaking like a misfire. First thought plugs and wires. Well by then it was late and Easter was the next day didn't get to it till Monday. Well after the change still crappy running.
So I changed the fuel filter and cleaned the mass air. No change. Checked for spark on the coil packs all have spark. Checked the PCV all good there. Checked for vac leaks none found. During that I noticed a small hole in the EGR tube I repaired that but still running like crap backfiring out the exhaust, engine shaking badly at times. I also changed out the FPR on the fuel rail. No change of course.
As of today I changed the coil packs. Again no change. Only code it throws is a EGR high flow after I fixed the hole but was having problems before that.

I have a 1998 F150 4.6 2wd regular cab with 255,000 miles on it. Lately it has had some problems. The first is that it will run really rough when under a load, meaning when I step on the gas. It runs smooth at idle and at cruise but when I step on the accelerator it bogs way down and almost shuts off. I have changed the spark plugs, spark plug wires, coil packs and fuel filter. Now I'm thinking maybe fuel pump?
The other issue is that when the truck is having to work a little harder (i.e. pulling a trailer or running in the summer with the AC on) it will start to run hot. I have changed the thermostat, flushed the coolant, cleaned out the radiator, etc. and it still does it. Could both of my issues be related to a fuel problem??

I have a 2000 ford explorer. 4x4 v6. One day i started it up and it was running rough. It had real sluggish power. Then the check engine light came on. I hooked it up to the code machine. The only readout was number 3 misfired. I replaced the plug and all was fine. A few months it happend again. I replaced it again and it was fine. Well it just happened again. I replaced it again. It ran good to work but on the way back no good. Light came on again. Hooked up the machine it read number 4 misfired and number 2 bank lean. So I replaced number 4. It still runs like shit rough idle and no power. Give it gas it dogs out but then it'll kick in if i get on it. Thinking it maybe a vaccum leak or intake leak or o-rings.

From cold, I start the van up, and if I just slightly crack the throttle it will start running rough. I think it goes away under heavier throttle...might just be that the rpms are up I can't feel it anymore, I don't know. It will idle just fine, and after it warms up it also seems fine. Where to look?Also I sometimes hear a very small, high pitched, vacuum leak from under the hood. What are the most common items that go bad, that I should look at first?

126000kms on 03 explorer 4.6 truck started. Running rough at idle and under load.... Code came up for cyl 8 injector. Replaced injector... problem still there. Switched cop and plug with another cyl and plug.... same code and cycl 8 is definitely not working. Would a generic problem always affect i cylinder. I even checked wire clip on for injector... it appears ok. There is power to injector wire clip.

2003 ford explorer 4.6L. This truck will start and run rough high temp low oil light come on and temp gauge is pegged hot. Oil gauge is fine though, checked oil its fine.
I checked coolant reservoir its ok.
If I shut truck off and restart it will run ok and rev like normal and then all of a sudden go into limp mode and will misfire etc...
What sensor seems to be the main culprit?cht sensor???

I have a 2003 Ford Taurus. It has been running rough for awhile. It doesn't happen all the time, alas. I took it to my local repair guy. They first said, oh this happens when the AC is on. But I knew it happened otherwise.
The check engine light came on yesterday, blinking, but didn't stay on. And it was running rough. Check engine light came on, on a Sunday so I had to wait until Monday to bring the car in. They just called and said they can't find anything wrong, ran it on the computer, says it's running fine. I said, did you check the spark plugs, wires, etc? (I am good at googling, to be armed with some kind of info)
I am thinking they just put it on the computer. I suppose it has to be running bad to show anything (?) and even then, it's no guarantee. Anyway. It seems like I am "sentenced" to driving this car until it strands me, catches on fire (I read about that possibility and I have on occasion smelled something burning), or if luck has it, when it is running rough, and I bring it in while it's running rough, the computer finds the problem.

will it hurt my 98' forester to drive it when one cylinder has no compression? They tell me it needs a valve job for 2,500. They already put a mass air flow sensor in, and replaced plugs and wires. Still got the miss, but I need the vehicle.
