extremely high idle

[luke87]

ok sooo..... i got in my truck to leave work to night and the truck decided it wanted to idle at 3000 rpm. it wouldnt stop at all. what could this be? maybe  the throttle body position sensor? is there such a thing?

 

any body got any ideas let me know? the truck is stuck at work. i had my budsdy come and take me home.

It's either that or you have a large vaccum leak.

can't find any vacuum leak. I did however take out and clean it and messed with the TPS...got the idle to settle down for a little bit, then my egr started makin noise and is messed up now....its like its sticking, and when it does, the idle goes way up, or way down.

If its not one sensor its another!!!! I'm just going to replace all of them! 18 years old now.
