i really haven't dug into it yet, but i was just looking for somewhere to start. first off the plugs look like they are getting fouled this makes me think the HEP or coil needs to be replaced. could it be the O2? or MAP? reading wrong? only code coming up is 36? would that do it? thanks - Dave

have you checked for trouble codes yet? I would assume if the MAP sensor is faulty or giving funky readings it should set the check engine light on.

yeah i stated in the first thread the only code i got was 36. wastgate solenoid?
