Wot was with a new sensor, autozone special. .02vac at stud on the back of the alternator. I had similar issue once before and replaced the ecm and everything was fine. Is it possible that the pcm can be frying the ecm? I have cleaned the grounds and even ran the truck with alternator disconnected with no improvement

01 24v would loose throttle and surge going down road so checked ac voltage and no issues there so put scanner on it and watched the graph and it was freaking out for Tps. So checked temp and it also freaks out on the graph on scanner when throttle cuts out. Went to install new apps and either no voltage at pin or reads 4.6 v on new sensor started truck and goes wide open
