LT1 misfire after new opti, plugs and wires...
It started misfiring after I (stupid) installed a dc-ac converter. Have changed all the mentioned things but it still misfires.
Must be something with the PCM or an el problem.
Any suggestions????

start with the things you changed 1st
check and then recheck the routing of the wires too make sure they are on the correct opti "port" and vice versa at the plug
did you gap the plugs or atleast check them before install?

OK. The car was running just great until i installed the converter. THEN it started misfiring. I asked people what tha cause could be and they said opti wires and plugs. I changed all that but it STILL misfires.
It has to be something electrical then. pcm stuff. Dont know to much about that stuff...
