WHAT WILL CAUSE A ECM CODE #34 AND HOW CAN I REPAIR THIS SO TH CODE WILL DISAPPEAR? WHEN MY SERVICE ENGINE LIGHT COMES ON THE CAR RUNS LIKE THE TIMEING IS RETARDED ALOT. I CAN KILL THE ENGINE, RESTART IT, USUALY THE SERVICE ENGINE LIGHT WILL GO OFF AND THE CAR WILL RETURN TO NORMAL PERFORMANCE.WHEN I READ THE ECM CODES IT SHOWED ME (12,34,12)
ANY HELP WILL BE GREATLY APPRECIATED

Thats a MAF code, you may need to replace the relays or even the sensor.. try taking the sensor out and cleaning it off with carb cleaner, and cleaning the relay connections off.

If it still runs bad, disconenct the sensor and try running, if your car runs alright the sensor or relays are bad. Replace the relays first, they are like 10 bucks each.. A remanufactured sensor shold be about $135, new $450.

 

I FOR GOT TO MENTION I REMOVED THE SCREEN ON THE MAF. NO OTHER MODS TO TH MAF. COULD THIS BE THE PROBLEM

 

Could be. The code is low detected airflow from the MAF. It could be that your tubing is loose post MAF, your power relay could be bad, or ultimately your MAF. Do me a favor though... DON'T squirt that thing with carb cleaner. It's a good way to ruin it.
