Engine/Transmission (1998.5 - 2002) Need ECM help in SE MI

[Weatherman1964]

I've got numerous codes and drivability issues on my 2001. I believe swapping the ECM is the best test. I cannot find an ECM to use as most of our trucks are still on the road. If you have one, I'd appreciate an email or PM and determine what to do from there. The truck is a 2001 auto trans.

I have so many codes for bad sensors or wrong voltages that it has to be the ECM at this point. Code list is as follows: 113, 121, 118, 236, 238, 343, 523, 563, 622, 753, 1475, 1693, 1765. Most are voltage related, gauges, and sensors reading wrong... it can't be all of them. I disconnected the EDGE box and the APPS has been changed. I have good fuel supply, 15p. s. i. all the time.

Symptoms are: erratic idol, gauges reading high, dead pedal when accelerating, slow to respond pedal, low power, max speed on highway = 63mph. LIMPING is the best way to describe it. 810. 397. 0820 if you can help. If I don't answer, leave a message, I will return your call soon.

Thanks, Kevin

Check for bad ground.

Bad grounds is what everyone has said. I'm not sure I found them all. Problem persists. Anyone know a good way to run another ground to the ECM?

Go to Radio Shack and get a can of electronic cleaner and spray the input to the ECM also spray the input to the PCM. Spray the wire ends and the ECM and PCM I think that will solve your problem
