The box has Standard TH420. It was the only one offered at the parts store for my truck.

When i start my truck it has no throttle response (dead Pedal), I let it idle for about 5 to 10 minutes, turn off truck and restart throttle response returns and it runs great. I have replaced the Throttle position sensor and still has same issue. I have tried to check for AC noise but don't have the right tester, i have removed the 140 alternator fuse and it still has same issue, next stepp is to remove alternator and have it tested. Any other option would be greatly appreciated. Thank you
