The car had oil leaking from the oil cooler into the antifreeze lines. I replaced oil cooler,the thermostat modulator, and the valve cover. I cleaned out the radiator reservoir tank and replaced all the rubber and plastic hoses. I have replaced both the throttle body and the accelerator pedal, but the car keeps going in and out of sync. I checked all wiring harnesses and scanned the system. When the power loss indicator comes on, I lose low end power. The scanner indicated the accelerator was at zero, but the throttle body was at 23 percent with the flap closed. The car clears all its alarms and runs great, but then the alarms will return and I am right back to square one.

I believe you have to perform the GM throttle body relearn process for it..
Pull the neg off battery and let sit for 30-45min to reset, then
reconnect and turn car on and let idle for 3mins and turn off and let sit for 1hr
repeat turn on and idle for 3mins then off for 1hr
turn on let idle for 3mins then go drive it and drive for 15-30mins doing over 45mph.
if that doesnt relearn it, you might have to take to a tech to do it
