1997 Chevrolet Tahoe LS 5.7L Heavy Pinging
Posted to GM Driveability on 9/1/2004 4 Replies

My wifes vehicle, when climbing a steep grade the truck pings like a banshee. Street driving no problem, full throttle starts no ping detected, just on steep grades. Any GM Techs seen a flash for the VCM or a fix for this problem.
