Hey first of all i am new to this forum, thanks for all the help and information.

Ok so sense i have owned my neon se 2003, it runs real rough and rumbly, seems like it has a misfire?? i replaced the plugs wires coil pack and all that. still rough do not know where to go from here.

Anyone else has this problem or know what i should be doing to fix it??

 

Check engine light on?

 

It comes on sometimes yes. I assumed it was the battery going dead due to it not starting sometimes. i just disconnect the neg battery cable and re-connect and it goes away and starts.

 

You can check the codes by turning the key from off to on 3 times quickly, ending in the on position. The codes will display in the odometer. Based on what you've said so far, I'm going to guess something like P0344.

 

yeah the code i got was misfire,,, but that tells me nothing i knew it had a misfire lol

 

as soon as i get a chance i will go downstairs and check it out for yall give you the codes.
