I checked the alternator and it was actually bad, so I put a new one on it and still have the same issue. so should I start checking all my grounds?

So after reading most of the forums i could find im still haveing the wide open throttle issue. I put a new APPS on it calibrated it started the truck up worked great. But if i turn the truck off and start it back up its wide open throttle again when i touch the gas then back to idle when i let off. But i can unhook the battery cable for 20 minutes or so hook it back up start the truck and it works fine. Any help or suggestions would be greatly appreciated, thanks.
