Ive got an 04.5 cummins with a quadzilla adrenaline programmer. Two weeks ago i got a sudden increase in idle, turned the truck off, started it up and I had a dead pedal. Called my mechanic, he came by and hooked up his diagnostic computer and it read throttle position sensor malfunction, he reset my TPS and it worked fine for two weeks then the same problem happened to me a couple days ago. I reset the tps again and it happened again the nxt day, the computer was reading tps malfunction again. I went ahead and bought a new tps $370 later, installed it and it worked for one day and the problem is back. Same as before, I get a high idle when i put it in park, turn it off, crank it again and the dead pedal was back! So i went ahead and reset the tps again and unhooked my programmer to see if it would solve my problem. It worked fine for one day and the problem is once again back to haunt me. I checked the wiring that hooks to the tps to see if i could find a short or a spliced wire and I didnt see anything. Since I messed w the wiring, my throttle is very delayed and sluggish in park, and when put it in gear its got a dead throttle. Any suggestions anyone what the real problem could be?
