Just got that one code P 0304 for misfire on cylinder 4. I went to autozone and had them erase it. Came back a week later. I change the spark plugs but I do not feel any sputtering. Car drives normal, no sputter or nothing. It just gives me that code. Think it could be the injectors? It's an 2003 dodge neon srt-4 stock with 63000 miles on it.

 

i would say start with the plug wires first. then go from there. and make sure you gapped the plugs what kind did you get?

 

I got the autolites copper platinum. I gap them at factory settin .055.

 

i would suggest a set of ngk 4306 and gap them around .045. ive heard many of times that platinum in turbo cars are a no no the tips can get too hot and actually break off, not good, thats why they made iridiums. in my opinion they are the best but in a stock car the much cheaper copper ones are fine.
