chugs down the road, stalls at low idle.
have replaced fuel filter, O2 sensor, alternator and belts, recently fixed supercharge. Some days runs just fine, other times it chugs, like its not getting gas. Usually this chugging lasts just a few seconds, however, now it stalls in idle, at stop signs; even when on cruise control at 70mph. very frustrating, keep fixing, something else falls apart.
sounds like you have a plugged Cati
IAC...idle air control is on these...trouble~
