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.
View 9 RepliesDad'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?

View 3 RepliesI 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.
View 4 RepliesI'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.
So I dropped my prius off to get looked at for error code p0301 number 1 cylinder missfire. They ruled out Spark plugs, coils and fuel injector. What else is ther? Also could it be the battery or even gas?

View 9 RepliesI've had the plug wire for my #4 cylinder burn out twice in the last 6 months. The car started running like crap and threw a CEL, the code was for a number #4 cylinder misfire. When I pulled the wire it has obvious signs of being burned out, like white powder and burn spots near the base of the wire where it goes over the plug. The plug and coil both look normal. No issues with the other cylinders. What could cause it?
This is on my '05 Santa Fe, 2.7l, FWD auto, with 180k miles
1999 ranger 155k 3.0 flex fuel. 304 is misfire in cyl number 4... I replaced the plugs and wires and checked the coil. the compression in cyl 2, 4, 5, 6 and got 80-90 psi so they are consistent but consistently bad right, it may be my compression tester.
The #4 plug was spotless after running 5 min, the #5 plug had some black on it already. Its hard to tell but it seems I had fuel residue on the plugs on cyl 5 and 6 but none on 4? Whats next pulling the intake to get to the injector?
Where can I purchase a distributor for a 2003 Dodge Neon SE?
The engine is running rough, the gas mileage has degraded, and the Check-Engine light is ON.We went to an AutoParts Store to have them read the car's computer output to tell us why the Check-Engine light is ON.The results said that the No. 4 Cylinder was not firing consistently.We replaced all four spark plugs and the spark plug wires. It ran a little better but the Check-Engine light is still ON and the engine still runs rough. I think we should replace the distributor or maybe just the distributor cap (if possible?).
My 93 year old dad has a 97 Dodge neon with a leaky brake line. He says it's the line that goes back to the passenger side back wheel and he feels that he can just tape up the leak. I think he is crazy, but he says the tape will be fine and work just fine since he doesn't drive the car that much. So my question is what would be the best type of tape for him to use? Since I know this won't work, what is involved in fixing a brake line with a leak?

View 5 RepliesI have a 2001 Dodge Durango, I just changed the catalytic converter, the truck acts like it isn't getting any gas, when I drive it above 65 mph for 20 miles, but I can pull to the side of the road for a min or two and go again, it keeps doing this. I can drive it all day in town no problem. Comp. says misfire on 1,2,,&4.
View 3 RepliesI have a 1993 dodge ram 15 passenger van. When it is cold, it runs fine, but after it warms up it starts to miss on the 6th cylinder. We have checked the plug and wires. Did not get anywhere. We replaced the injector. No dice.
View 8 RepliesMy 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?
View 11 RepliesI have a misfire on the number 2 cylinder on my 97 Nissan Maxima 5spd. The computer has been changed 3 times, and it'll work for a short time after the new computer is installed, but then the problem resumes. What would cause this to happen? The coil has also been changed.

View 8 RepliesMy truck has developed a misfire on cylinders 1 and 5. The OBD2 scanner at autozone says code P0300, Po301 and P0305. I bought a new set of plugs and wires. Problem still there. I then replaced the both coils. Problem is still there. Is there a control module or something that could kill those 2 cylinders like on the older trucks with distributors?

View 14 Replies1997 chevy k1500 ... I have a misfire on cylinder 3 that i cannot figure out the cause. The idle is rough, backing out after starting is very rough, it seems to pick up at higher rpms but once the truck upshifrts to the next gear it shakes like a leaf in fall. within the past year the engine was rebuilt all new seals a new fuel pump, new injectors, new everything practically. so far i have done the following:
compression test results:125-130psi
fuel pressure test results: 50psi once primed, 50psi with engine running, no immediate pressure loss after engine is shut off
new spark plug wires
new spark plugs
replaced all four o2 sensors
