1991 GMC C1500 Sierra SLE 5.0L Poor Idle Quality, Hesitation, Surge, Stall
Posted to GM Driveability on 7/25/2003 14 Replies

hello fellow tech`s this gmc 1500 is driving me nuts- the engine in this was replaced ~ 3 years ago - it never seemed to have enough power but no problems other wise .

Now over a period of time the engine has started to ping excessily & fully retards timing ....
