Misfire Question?!?!??!?
Right before I took my car apart for my cam install my opti took a **** on me. Well Im done installing my cc306 now and I put a USED opti back on it and it still has stock tuning for now. I pluged my GM Tech 2 scanner in and got a misfire chart and cyl #8 is missing almost everytime on anything under 3500 rpm and cyl#6 is missing part time while #4 is just every now and thin. Well my question is should it misfire like this on the stock tuning or is my new used opti just SUCK and is taking a **** on me?????
Any ideas?????
