Hi. I normally don't ask for help... but uhh Please Help! If anyone has any idea of what this could be or if it had happened before and was solved. (most similar issues i've been finding on here have not been fixed or updated)
Car is very hard to start.
In order to turn over, i have to pump the gas pedal a few times while cranking.
Once started, i have to keep the idle above 2K rpms at about 50% throttle to prevent it from stalling. Also there are clouds of unburned fuel mist coming out of the tail pipe. As soon as i left off the throttle, engine dies instantly.
Gas in the crankcase. (I'm assuming from the cylinders being flooded and seeping past the rings.)
Codes:
12: Mass Air Flow Meter Sensor
21: Ignition signal in the primary circuit is not being entered to the ECU during cranking or tuning
34: Detonation (Knock) Sensor
This all started by a misfire caused from a faulty #2 injector, at which everything else on the car appeared to be OK and in running order.
I've replaced:
- Injector #2
- Dizzy cap
- Dizzy rotor
- All spark plugs
- Fuel Pressure Regulator
What else could it be?
