Obly other thing I could suggest would be check your earth connections to chassis and motor since you have had motor out. Bad earths can cause weird stuff.


Maybe check batt/alternator volts to see its regulating correctly alternator is controlled via ecu, fluctuating batt volts could cause weird issues, should be pretty stably around 14 during normal operation.
I have changed all OCV's, cam position sensors, crankshaft position sensor, and ecu. Batt volts are stable. I will double check grounds and cam sensor clearance.

How much advance should the intake cam's be capable of? I am seeing both intake cams do not want to go above 38-40 deg.
