Well I have done everything I was told as for the IAC valve and TPS cleaning and adjustments and I will say that my engine is finally idling by its self. The only problem I have is that the engine is idling rough, could it be fuel pressure, or a weak ignition coil? I am running a crane compucam roller cam, " factory", and they suggested using an ajustable pressure regulator and that is the only thing I have not adjusted. I am however reusing the factory ignition coil. Any thoughts would be helpful thanks. Could the TPS need replacement? What about possibly changing the ignition coil to a hotter coil, or just replacing it?
