so my m42 sedan is running absolutely terribly. It started out of nowhere and I diagnosed it to find that the o2 sensor relay was dead and the ICV was frozen. Ok cool, I replaced them and threw new plugs in (NGK BKR6EK) the car idles now rock solid. no misses or anything.
if you go over 15-20% throttle the engine does nothing. you hear the intake wide open but no power whatsoever. its as if the ignition is turned off, but the tach doesnt drop or anything. the throttle response all around is SHIT. if idling I can go WOT and the idle actually doesnt change just the engine starts missing like a mofo
the car runs better in open loop than closed loop. from what I have diagnosed all the engine's sensors are operating correctly (coolant temp sensor, AFM, TPS). I had a fuel pressure gauge on it last week when diagnosing and it read in spec with no jumps or anything.
I do NOT want to miss the picnic, please help me figure out what sensor is causing this. TIA fellas... Im pretty stumped
