Just swapped the motor out of my 99 for an 01. It has been a massive headache due to the guy I bought it from but beside the point. Motor runs great. Won't heat up due to the fact I think I have a bad thermostat. Truck runs great down the road for about 5 seconds then does this dead pedal thing but if I let off and get back into it it's fine for another 5 seconds then it does it all over again. I am running the 01 ECM. Left the programmer off for the first trip so it is bone stock other then intake and exhaust. Performance Engineering just redid the head so that is all new. Any advice is greatly appreciated. Thanks
