It was misfiring, not just random

well I changed that spark plug, yes i only did the one so far because i wanted to test out if it would fix it. So i changed it, and now it's just all messed up, first time i started it, it died on me really quick. 2nd time it toke a bit longer but same result. but then all the lights everything from vdc lights to the slip one.

I have videos of it i will find a way to get them posted on here tonight. I think next thing i would change would be the coil?
**and never mind on the videos..some how i didnt record it other then it setting at idle normal for a few seconds

See if any other codes popped up, feels like cam sensor.

Zredman

should i drive it to get it the code read again? or try and get someone with a obd II reader?

Neimad

Drive it for a block or two, search the forum for the trick to make the MIL flash the codes for you.

Zredman

couldnt find that trick ur talking about, and i put it all back together, cleaned the TB and it worked fine...for about 2 blocks, then light came back on and sounded and felt like a misfire again.

Zredman

so if wasnt the plugs?? what else would cause it to misfire?

Ignition coil

Zredman

anyone know who makes the ignition coils? and as far as price goes, i know autozone sells them about 100 each, but im finding a few online for 40-60 range what are your thoughts on that?

Hitachi makes the OEM coils.

Don't buy anything until your sure its the problem. Switch the coil to another cylinder and see if the code jumps. You didn't search hard enough, it's real easy search 350z check engine pedal flash:

He's correct. Clear your check engine light, swap the coil in cylinder 2 with another. Wait for a code and your p0302 should change to p030(cylinder you swapped the coil with).

Zredman

switched coils, problem followed but it showed 2 errors, both same cylinder but idk..http://sphotos-b.xx.fbcdn.net/hphoto...84287707_n.jpg

Code jumped to 304, 302 is gone?

Zredman

Ya it jumped with the coil. But it gave me 2 p0304 codes in the pics

Neimad

Thats odd but no big deal, you figured it out; change coil.

Zredman

ok its almost all fixed up, but now its idle is all off, starts at around 1.5 rpm then slowly lowers its self to 500rpm. going to try and do the ecu reset stuff tomorrow and hope for the best.
