Hi, just finished swaping m52 into my 318is and now i have a bad missfire under load, mainly when the engine is warm. it looses a lot of power but will kick in the upper rpm range. when i scan it does not show any missfire codes. did have a code for the vanos actuator but that code hasnt come back after clearing it. any ideas? btw, trm tune, s52 cams, new vanos seals,new crank sensor, new cam sensor, obd-1 fuel rail and manifold. thanks im lost on this one.
