Had a rough start on Sunday evening after shift, kept idling above 1500 rpm, for about 10 min, would rev it and the rpms still wouldn't come down below 1500 rpm, shut it off, restarted it and it drove home fine, went out to a buddy's house, and on the highway back the engine light came on, and was bogging on the highway out, felt like missing,

Came home showed the code p0122, tps, cleared code, started, all good, this morning all good on the way to work, then the code came up after work, cleared it again, and it's still coming back,


Just replace the tps? Or should I do all the throttle body sensors with it?

Any thoughts?
Thanks guys

Replace the TPS and give the IAC a good cleaning. You should be good to go.

Weird, I ordered the tps, will be in first thing tomorrow, will take it all apart and clean it then, engine kit was on on my way to Tim's/crap tire, off on way home?

I cleaned the IAC with the new tps sensor, no codes yet, starts up smooth, but when the idle comes down it jumps between 500-750 rpm, bouncing up and down, almost dying, any tips?


I think that must have just been first start up with new sensor, she's running smooth every start up since, problem solved
