so i got my art pipes and tdx2 exhaust installed like 400 miles ago... then i got this light today after starting my car. is it because im running lean?
i also have a cai and 5/16 spacers on my car as well.

if i am running lean, would a simple uprev tune fix it?

 

Check the code... Order an ELM327.

 

You gotta know a dude with a code reader..? If not, come on over I have one. Haha

 

just used my buddys scanner, turns out i have code p0302, cylinder 2 misfire lol. faak

 

Those are usually easy. Spark plugs come to mind. Have you changed them lately or not changed them in a long time?

Or a coil pack.

 

its both i think, yeah i did.. im guessing the shop i went to didnt do it right?
ngk spark plugs btw

 

Take it back to the shop and have them check their work.

 

Fixed the problem today, wasnt the spark plugs, my coils were causing the misfire, cylinder 2 and 6
