STS Scott Posted March 21, 2005 Report Share Posted March 21, 2005 Just before I went away for vacation, the STS began to develope a hesitation, similar to a few months ago, before I replaced the wires. It is regular now, and is definetly a persistent problem. The contition comes and goes every few seconds as you accelerate, and occasionaly will backfire. I am assuming the problem is spark-related, but what do you guys think? Thanks!

KHE Posted March 21, 2005 Report Share Posted March 21, 2005 How many miles are on the spark plugs? I had a similar experience last fall with my '96 SLS and 6 of the 8 plugs were missing the platinum pads - the gap was almost .080". A new set of Delco plugs solved the problem.

STS Scott Posted March 21, 2005 Author Report Share Posted March 21, 2005 Hmmm, how many miles on the plugs? They have not been replaced since I have had it, which has been for the past four years. The car currently has about 180,000 miles on 'er. I'm pretty sure they are the original ones. I guess that will be the first step to take.

PAUL T Posted March 21, 2005 Report Share Posted March 21, 2005 Yes, start with the spark plugs and if that does not work get a new coil for about $40-$50 and try replacing them one at a time. Link to comment Share on other sites More sharing options...
Ranger Posted March 21, 2005 Report Share Posted March 21, 2005 If you have 180K on the plugs, like Guru say's, "They don't owe you a dime". That's where I'd start. Link to comment Share on other sites More sharing options...
STS Scott Posted March 24, 2005 Author Report Share Posted March 24, 2005 Problem Solved! I had the plugs replaced today with 8 new AC Delco's, and all is well again! Thanks for the tips guys!
