1994 Camaro Z28 stalls while coasting
#11
My mechanic drove the car with his scanner attached, and when it stalled, he recorded the event. It recorded the following codes:
41 - EST circuit voltage was above 4.6 volts when engine speed was under 1500 RPM.
42 - PCM did not detect any EST signal within 84 crankshaft revolutions.
36 - ECM detected less than 40 high resolution timing pulses between each low resolution pulse for 5 consecutive cycles.
44 - Left oxygen sensor voltage was under 0.2 volts for 50 seconds of closed loop operation.
48 - There was no MAF signal when engine was on.
18 - Injector driver circuit voltage to PCM was wrong for 4 seconds.
51 - PROM error.
He is going to clean off all the connectors at the computer, and then I am going to raod test it again with the scanner attached.

you have an electrical nightmare,,, if somehow "cleaning off the sensors" works then its magic because thats a retarded fix, if the car runs at all its connected enough, find a new mechanic and replace your sensors, or buy a stick like a real man hahaha

Well, it's been 3 days and 375 miles in L. A. traffic since the contacts were cleaned, and not one single stall. I think I'll keep my mechanic, and my sensors. As far as a manual trans goes, I find it hard to push the clutch in with my prosthetic left leg, so you can keep that too.
