Dodge - Neon :: 1997 - Check Engine Light Has Been On And Causing Random Misfire
Sep 1, 2011
I have a 1997 Dodge Neon with about 153,XXX miles on it. My check engine light has been on and i know that is caused by a random misfire. But more recently i went to start my car and it started but ran for less then 10 seconds and died. I tried to start it again and it wanted to but wouldnt make the final step i guess. We checked my spark plugs and i had oil sitting in 3 of the 4 there are. We have tried starting it again after cleaning the oil out and it started on the first try, I am just afraid of messing anything else up so until we figure out why it did this to begin with the vehicle is off limits. My Fiance said we need to replace the spark plugs and a gasket.

My dad has a 97 Dodge Neon 4 cylinder. The car has been leaking oil, and on Sat the leak grew and was real bad. He took it to the only shop he could find open who put it up on the lift and said the leak was coming from the front of the engine. On monday they did the work ($286) and told my dad it was a seal on the front of the engine behind the flywheel. My dad is old and doesn't hear well and the mechanics english was not real strong and his writing on the recepit is not real clear. As I am worried my dad might have gotten taken, is there a replaceable seal on the front of the engine that could go and cause a leak? They showed my dad the leak as the car was on the lift and running as that was only when the leak occured. I am concerned my dad was taken. He says he drove it around and such and didn't see any leaking when he picked it up and left it running in his drivway for a while upon getting home and no leak. Just wondering?

Dad's 97 dodge neon still showing a CEL and a code for a misfire but according to code reader it has something with the fuel line that is causing not enough fuel to get to engine. Car has a new fuel pump (about 6 months old) and it runs fine for a while then will sputter then will run fine for a while and back and forth. What it might be?

My 95 Dodge neon had no problems it ran, started, drove fine everyday! Check engine light turns on after few drives... Now after about 10 drives the car does not start. It makes a rapid clicking noise.... Called auto shop they say battery, I bought this battery one year ago from them. They suggest i try a jump start. I go to jump start, look down check engine light is FLASHING.... Since car wont start, needs a tow for a car I'm not even driving nor will drive and not worth my money to invest anymore.....

My dad's 97 dodge neon is showing a misfire in the number 4 cylinder. He replaced the spark plug but still getting that code and engine not running smooth. What other things could cause this? Engine has about 130,000 miles on it, had been running fine.

2005 Dodge Neon SXT 2.0 engine
At first I would have an intermittent jumpy speedo then today it got worse and all of a sudden the check engine light popped on. Got it scanned and had three transmission related codes come on including the gear one incorrect ratio code (can not remember the other three). My first suspect was the VSS output. Replaced the sensor and took it for a test drive; no speedo no shifting. Took it back and and got a new one same issue with the replacement.
The tranny fluid was recently changed just after 203,xxx miles. Believe I am the third owner of this car. Seems to have been well cared for in the past. Recently also did some other work that was not transmission related when I first purchased the vehicle.

I have a 2001 corolla with 37K mi on it. The check engine light came on today. Took it to advance auto parts to read the code. It showed P0171 (System too Lean) and P0300 (Random Misfire). Called up a toyota dealer and the technician think it might be bad gas. I buy gas at name brand gas stations and sometimes from BJs. I am not sure if the problem is with gas. I also been up to date with maintenance.

I have a 96 Grand Voyager that had had sat for a year undriven or started due to being out of state. It ran like a champ when I parked it. Now I charged the battery and went for a drive on the freeway and my check engine light came on and started blinking. I had the code read it came back with 2 codes a P0306 and a P0300. I noticed that the cylinder 6 spark plug wire was arcing on the core support. So I replaced all the plug wires and spark plugs with Champion platinum spark plugs. I cleared the codes and took it on a test drive and the P0300 code came back. Is there anyway the old gas is causing the random misfire? or what else could it be?

I have a 2008 RX350 with 68k on the clock. Received a check engine light for random misfire (P0300) and misfire on Cylinder 4 (P0304), Cylinder ,5 (P0305) ,Cylinder 6 (P0306). Question is what will be causing this to happen. I thought about changing the spark plugs to see if this is possibly the cause. but what else should i be checking?

I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?

2004 Elantra AT ... 6 months ago top of the radiator cracked caused it to overheat and blow the head gasket and warp the head. Repaired that and compression is fine now. It ran great for 4 months but now it randomly stalls. at or near idle. Seems to do it more at operating temp rather then cold. Occasionally the check engine light will pop on and the code reads (random misfire). It acts just like it has been shut off. But immediately restarts.

The check engine light keeps coming on and off on my 2001 Echo with the above code. The car runs fine and the check engine light randomly comes and goes. What would set off the check engine light, but not cause noticeable change in performance?

Just started getting a p0300 random misfire code on the durango a couple days ago. pretty sure it isn't moisture related since it started on a nice sunny day. it was running pretty rough so it was obvious that it was misfiring. I changed the plugs since it was about time anyway, and they needed it and I cleared the codes. new plugs (put in the oem champion copper plugs) didn't make the problem go away. The engine still ran rough and the code came back. 2 of the plugs looked like they may have been fouling a little bit. they were a fair bit blacker than the rest of the plugs. I went ahead and changed the coils on those two cylinders and reset the codes again. Still runs rough and the p0300 came back. where do I go from here? I am not getting any specific cylinder codes so it makes sense to me that it isn't one or two cylinders not getting spark. 2003 durango 4.7 ....

So I have been having some troubles with my 2003 F150 4.6L ... Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors??? I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?

1997 Ford Ranger with 190K miles has check engine light on with P302 computer code, meaning misfire on cylinder 2. Engine runs rough at idle only once it warms up, which only takes a minute. It is usually fine while driving, but it's a lot easier to feel a misfire at lower RPMs than at higher ones. Added fuel injector cleaner to gas for a couple tanks, no change. My mechanic has checked spark plugs, fuel injector, o2 sensor, and everything is ok. Dry compression test shows good compression. He thinks it may be a valve sticking, which means a valve job: expensive. Is there anything else that can be done? Why is there no misfire when it is first started?

I've had problems recently with my 03 Neon:
1) The CMP sensor throws codes constantly and the car is really hard to start at times. I replaced it a year or two ago with a generic part. From what I've read elsewhere, Neons hate non-Mopar parts for this so I just got a Mopar replacement and will drop it in when I get the valve cover back on. Does it make sense that a replacement could go bad w/in 20k miles or so?
2) Cylinder 1 misfired pretty hard. I accelerated on the highway and heard a thunk or thud w/ a loss of power. As the only code I got was a misfire I drove it home slowly (about a mile). Could this be caused by fouled plugs from the repeated hard starting? (I lived with the CMP sensor being bad through the MN winter cause I didn't want to replace it until it was warm). Should I look into this more? The thunk really worries me...
3) Last spring at about 95k miles I noticed what felt like my clutch slipping a lot. It would almost always slip under even partial acceleration at highway speeds and occasionally at lower speeds. I'd notice the rev increase w/o increasing tire speed. I took it to a major chain and they took a week to replace the clutch... but ever since then I've felt occasional slips. Did they do their job? Or is there something else here? I don't have a tach but I have a scan gauge ii hooked up which does show rpm increasing significantly w/o speed increasing.

I have a 2001 Mazda Tribute with 141,000 miles. Recently, I've burned up both O2 sensors causing the check engine light to come on. My mechanic has replaced each and they've burned out again. The head gasket was replaced after that, to no avail. The check engine light continues to come on after being cleared in the computer. I have also noticed that on humid days, the car misfires on at least one cylinder., but any other time, it seems fine. What to check next? My mechanic is at a loss.

2001 GL 1.5 Litre. Car occasionally hesitates a little with AC off, but runs pretty well. But with the air conditioner on?
Stalls about 50% of time when backing with A/C on. From stoplights, sputters all the way through intersections with A/C on, sometimes backfires. On a few occasions, the Check Engine light will blink on and off while it's doing this. After it gains a little speed/rpm, though, it's all good again, light goes back off.
Had full tune-up just before we bought it 4,000 miles ago. Air filter clean. Not sensors, because the CEL goes back off by itself. What the heck? How could the A/C cause a backfire?

With a 100 k on the odometer, the wife reports that the car started shaking, trans was slipping and check engine light came on after driving about two miles. She drives it at low speed back to the house. Investigation under the hood shows trans fluid in the radiator and coming out of the overflow tank. Engine starts right up and we have not had any other driveline problems since owning the car in 2005.

While driving up a long hill on the highway, one of the cylinders quit firing causing a bad engine vibration and check engine light. I turned around and drove home, pulled the plugs, and found the plug closest to the passenger side had bridged. I'm not sure why; it almost looked like it melted or had some sort of physical damage. This was on a 2013 Sonata Limited 2.0t with 45000 km / 28500 miles.
