Posted to GM Driveability on 12/17/2009 56 Replies

engine developed a backfire through the intake. Other shops have attempted to fix with no success. coil puts out 30kv. engine backfires when snapping throttle, also when accelerating agressively. all sensors show good responce and accurate readings.
