Posted to GM Driveability on 12/3/2003 13 Replies

fellow techs, need help... have installed new iac valve and cleaned upper engine, when the vehicle is put in reverse and the wheel is turned, the vehicle will die, not every time though. have checked inputs to computer such as t.p. map, etc... seems to me that...
