Re: '01 Express 3500 high idle
Have you looked for any vacuum leaks in the area of the TPS or IAC. Possibly a bad vac hose that you reconnected when working then worked itself loose?
Just a WAG. Possibly an electrical connector that was marginally connected that you bumped and reconnected while working and then worked itself loose again? Have you scanned for codes?
FWIW
YMMV
