okay so i went back to mpfi.i swapped everything correctly,but,its when i press the gas pedal it bogs out.i swapped from the pm8(piece of crap ecu)to the pm6.when you play with the throttle body it sounds good until you press the pedal.all gears when in drive bog out and the car shakes. can anybody tell me what the hell it is.my oil light comes on every now and then.maybe oil is too low cause my valve taps were noticable.please answer my questions someone
