Re: 1991 chevy 1500 5.7 tbi erratic idle
have a close look at the tbi throtleshaft for any play...if theres play it can throw your tps "throtle position sensor" off..if you havent replaced the TPS would do so as they wear and your trucks got a few years on it and dought prievious owner did...in anycase is one of them things to watch for with tbi's
