I've thoroughly checked the throttle body and cleaned it, the throttle linkage itself is fine, the idle hasn't been changed from its factory setting - all of the cables are fine and the pedal is free and clear from obstruction.
The only things I've yet to check are the fuse panels in-cab and underneath the hood, and they're about to be next (covering all my bases) but I'm left scratching my head as to what could be wrong.
That leaves the TPS among other things - but, before I consider hauling it off to the mechanic, I'd like to keep working on it myself.
Any gurus with any good guesses would be very appreciated right about now. I'm about to pull my hair out. >=)
have the same problem?
