STS Scott Posted March 31, 2005 Report Share Posted March 31, 2005 The STS's chronic hesitation has returned once again. Roughly three months ago, I replaced the wires with some new AC Delco ones, which remedied the problem perfectly. Then 3 weeks ago, the hesitation/backfire condition returned, to which I responded to the problem with new plugs. The plugs that were being replaced had to be the original ones, as they had erroded themselves to oblivion. I was suprised they still had the ability to "spark", given the condition they were in. These new AC Delco plugs seemed to do the trick as well, but only for a short time, as the problem has returned again. The problem seems to keep "moving up stream", as I am now thinking the coils are the culpret. Am I correct in presumming the problem to be spark related, and not, say, fuel? What do you guys say?
