Yeah i have a 2.2 ecotec for a 2004 cavalier and I supposedly have #3 cylinder misfire code does anyone have any suggestions on why this is happening. Thanks
Whats the actual code, p0303? Could be a bad plug or wire.

Hey well thanks for the info appreciate it
and sorry for the late response i deployed for a while
update still got check engine with the ecotec spark plugs. next step coilpack
ok man i know your the go to guy man its still over the #3 cylinder misfire i checked the plugs there ok i've only had them for 3 months and there ac delcos cuz thats what i here are best for the cavalier engines i have a question though could it be the 02 sensor making this happen? another question is it possible to get fined or a ticket for having a vibrant exhaust catback cuz i keep getting pulled or and spent to much to just change it back they say its to loud and i don't even have aftermarket headers?
update they change a part on top of me engine. this part is rigth to the ''ecotec 2.2'' emblem. they changes all 4 sparks plugs too
i had this problem with my 2003 sunfire 2.2l ecotec , it would give the misfire on cylinder 2 and 3 , i had to change the spark plugs and the coilpack , for some reason i gad to change them both

The coil packs are known for going on these cars.
