it is possible that maybe your grounding out.. so when you give it gas something moves and grounds out, same for when shutting your hood. it would be kinda obvious to me that if i hooked up my alternator with faulty wires that a problem may occur... but thats me...lol

 

Code 12 is the diagnostic code. It also means that no reference pulses are being detected by the ecm. If this is the only code being displayed by the ecm, you are being told that the ecm is functioning properly.

Code 34 indicates a faulty maf or map sensor. The typical problems are usually false air, vacuum leaks, or residue build up on the maf element or behind the throttle plates. Check the wiring and connectors very carefully. This code is set when the ecm sees a indicated low air flow, or unrealistic high manifold pressure. Usually a bad map sensor is at fault, but check the wiring and connectors for shorts.
