Joel,

Thanks for the suggestion. Just got it back from the shop today, and idle is now up to 3500. Anybody got a clue what the heck may be causing this. The truck is now completely undrivable. The only reason I took it from the shop was because the mechanic was "going to have to start going through some wires". No thanks, I'd rather wait. Please help me out. Runs smooth, but idle is sitting at 3500rpms. Is there anything he could have done to change the idle speed, or any mechanical thing that could do this. Really need the Rodeo back on the road soon.
Thanks in advance, Ted.
