ok ive pulled the codes ! key on engine off test i got 66c, 67c,67o ! key on engine on test 12r , 42 relay and solenoid test 11 everything ok! cylinder balance test 90 everything ok!
oh one other thing when building the motor i used the idle air bypass gasket supplyed with my kit and blocked the idle bypass holes ! could this have anything to do with these problems ?
IF the IAC ports are blocked then the computer has no way of controlling the idle. If the idle setting just happened to be correct then it would just idle a little rough. If the idle setting was off, the car probably wouldn't idle at all.
Code 42 indicates a rich condition from the right O2 sensor. The sensor may be bad or an injector could be stuck open. I am not sure how to narrow that down.
Actually, try swapping the O2 Sensors and clearing out the memory on the computer. If the rich condition moves to the other side of the engine, then the O2 sensor is suspect. If the rich condition stays on the right side then look for an injector problem.
the kit im talking about was the head gaskets and upper and lower intake gaskets! they came with an idle air by pass plugs to block the holes! i dont know why i put them in and i had doubts before doing it and have had trouble since! it ran fine before i did all the mods and ran great with the mass air plugged in ! but since doing the work and putting those idle air bypass plugs in it wont run good while mass air plugged in! runs fine while unplugged!
Well, the fact that the car runs better with the MAF unplugged does not indicate a problem with the MAF. It only indicates that there is a problem with closed loop running.
