Need help...

[Chad05SRT4]

Okay, so I put a new UPP and mpx throttle body on my car and everything seemed to go smooth. Well when I started up my car it immediately jumped up to 2500 rpms, and won't drop. Anyone have any idea of what could be wrong with it. I don't want to have to take it to the dealership, but if that's what I have to do then that's what I have to do. Thanks for the help...

Make sure theres nothing obstructing the TB cable(like the clamp for the UPP)

[Chad05SRT4]

yeah that was one of the first things I checked. I took the new throttle body off and put the old one back on to see if that was it and the stock one is doing the exact same thing. I'm stumped...

tps installed correctly?

[Chad05SRT4]

I'm pretty sure...

vacuume leak? I would also check the tps sensor. wiggle the wires and see if that changes the idle

sorry double post

[Chad05SRT4]

Make sure you installed the Idle Control valve correctly.

I had the same issue a while back.
