High idle speed

[deweyville65]

Hey guys, anyone have any ideas here? Ever since I been in Az with this truck, after warming up the idle has been up around 1000 or so when coming to a stop. After being stopped for a few seconds, 10-15 i guess, it will drop to around 800. Seems worse with the A/C on. I know the computer will kick up the idle with the A/C, but this seems like excessive. I am wondering if the computer is wrong for this altitude, around 4500 - 5000 feet. I am not at all savy about computer controlled engines.

It does not sound that far out of pace for what they do. When I lived in Phx, that seemed to be normal, as compared to up here at much higher altitudes.

Thanks for your reply. Guess I'll just live with it.
