Subject: Re: 1997 GMC Sierra 5.7 by joeld on 2016/4/8 0:29:16 Glad it's fixed! And I believe it. I've seen many times on a high mileage/or old set of plug wire that were "OK" and the engine was running good until several wires were moved around. This movement was just enough to crack the wire and cause a mis-fire! Joel |
