Who knows this?

I think I've read numerous times that if you can unplug your AFM (with the car running) and if it doesnt affect idle, then the AFM is bad. You really shouldnt have to since the above is happening, but you could just test your AFM to be sure. I'm having this same problem warm engine = bad idle and i've narrowed it down to either a bad ecu temp sensor or TPS. If Maybe check TPS next

i heard that too but i wasnt sure, tps probably wouldnt effect idle so much, but more of higher rpm

figured it out, tps was bad, switched it with another, car runs good now haha tahnks for the help guys, the code 51 didnt show up when i checked codes when the car was off and then i checked it with the car running and it showed up, so i swapped it and now its fine .....hopefully
