lt1 surging at idle???? my 95 z28 started to surge at idle after a recent tune up, and recently it started to hesitate and backfire at WOT (every once and a while)
can it be o2 sensors?
let me know what you think

Did you take the intake bellow off? If so when you put it back on the bottom lip of the rubber probably rolled under and it's allowing unmetered air into the intake. At least that's what I have seen and had happen...
