when I step on the gas all the way my car seem to not really have much power and when im running on 20 pounds It will start jumping checked the engine at autozone and gave me p0422 catalyst below treshold (bank 1) andp0302 cylinder 2 missfire detected . Also the car does not have a catalitic converter after the turbo just a straight pipe what can I do to fix the problem ...

 

misfire is most likely a coil pack - switch the #2 with the another one and see if the misfire follows.

the p0422 is caused by your TP - check around for a DIY to get rid of it - its called a no-fouler mod I think

 

thanx for the help I already changed the coilpack and still giving me that codebut ill have to do the diy mod any more ideas

 

any more ideas about the missfire
