computer has been changed and fuel pump has been exchanged.
WOW!!! Perform some test & see where the issue is. Or tow it to any GM dealership & let them diagnose it
throttle position sensor , good call. also could be crank position sensor or cam position sensor, all have very similar symptoms
I have replaced plentum gasket, throttle body, o-ring gaskets, injector o-rings, fuel pump, i-ac motor, MAF sensor, and cleaned the entire fuel system. Has brand new fuel in it. It will not throttle up, acts like it is starving for fuel with the MAF plugged in. It will throttle up and down with the MAF sensor unplugged but will die when you let off the throttle. What am I missing? It is acting like a vacuum leak, I think that it is a sensor somewhere, or could the cat converter? PLEASE HELP I AM LOST THANK YOU!!!
