1993 Chevrolet S10 Blazer 4.3L Poor Idle Quality, Hesitation, Surge, Cuts out, Stall
Got a Vortec V-6 that surges badly at idle. IAC tries to keep up with it but sometimes dies. Injector pulse width surging up too, like it's trying to correct for a lean mixture. O-2 showing lean but we can't find a vacuum leak. Propane not helping.
