Posted to GM Driveability on 9/24/2007 18 Replies

any help appreciated, running out of ideas, am suspicious of aftermarket ecm & sensors as none of the parts are gm , had customer bring in all original parts he changed. idles very rough at idle driving down road seems fine no hesitation or surging.
