Thank you all for your input. The engine code was code 64 which was secondary air. Something or other blah blah blah. So it is safe to say it isn't the auto tune or pc5. Upon reading all your suggestions it looks like all I have to do is unplug the right side valve and wire in some sort of resistance to fool the ecu to thinking the pump is still plugged in. Now for the question ... After I do this will the engine light simply turn off or will I need to have the code cleared by a tech with a kawi scan tool?...
