1991 Chevrolet S10 2.5L Stall
Posted to GM Driveability on 11/3/1999

This one stalls at idle. All computer values o/k except when the stall occurs the timing goes to 50' advance for a very short time. The engine may die or stumble at this time. A movie on my snap on scanner shows only the timing advance to be out of specks....
