supreme_style21 Posted September 18, 2004 Report Share Posted September 18, 2004 Just my luck.. I'm 300 miles from home and the parts stores close in 40 minutes for the rest of the weekend. On the highway, any steady speed above 50 results in the engine stalling/sputtering back down to 50. Say I'm going 60.. its fine for a few miles, then it starts cutting out.. sputtering and jerking its way down to 50, then the cruise takes it back up 60 where it does it all over again. Does the same w/o cruise on, so thats not the problem. Any acceleration is fine and smooth.. its just when it maintains a steady speed is when it starts being a bitch. I don't quite feel like driving 50 on the interstate all the way home tonight. Front 3 plugs are ok. (Can't dig to the back ones just yet) Wires are not arching. WTF should I look for now? I thought perhaps a fuel filter, but WOT doesn't affect it at all. Coil packs are all original with 100k on 'em.. any way to test them? No SES light. If all else fails, anyone happens to see a white Grand Prix on the side of I29 or I94 tonight, feel free to smash the hell out of it, cause I won't be going back to pick it up. :cuss: Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted September 18, 2004 Report Share Posted September 18, 2004 any way you can get a timing light and attatch it to each spark plug wire? that might tell you if you have a bad coil pack. mine had those symptoms a few months ago; while driving on the highway it would be fine for awhile and then start stuttering. in my case it turned out to be extremely worn spark plugs with like a .060 gap :shock: sounds like a spark issue to me. good luck!

supreme_style21 Posted September 18, 2004 Author Report Share Posted September 18, 2004 No way to get a timing light to it. I'm gonna have to pull the rear three plugs and hope they're the problem. A friend had a Cutlass Supreme with shitty plugs and it 'feels' like the same symptoms after I drove her car. Only thing is hers would act up under acceleration.. once leveled out, there was no problem. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 18, 2004 Report Share Posted September 18, 2004 thats what my 95 did before the timing belts went. Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted September 19, 2004 Author Report Share Posted September 19, 2004 As soon as I pulled off the rear plug wires, I could see the problem already. The boots were FULL of corrosion for some reason. And I mean FULL! Kinda suprised it actually ran as it was! I cleaned 'em as best as I could with some emery cloth. I'll have to pick up a new set on Monday. Quote Link to comment Share on other sites More sharing options...
PeNZ Posted September 19, 2004 Report Share Posted September 19, 2004 did that help it at all? Quote Link to comment Share on other sites More sharing options...

DiscoStudd Posted September 19, 2004 Report Share Posted September 19, 2004 Condensation is more like it. I doubt any rainwater could ever reach the sparkplugs like that... Just gotta add my 2 cents. When you change the plugs and/or wires, get a tube of Dielectric Grease and squeeze off a good amount inside each spark plug boot (both ends.) That way it'll keep all of the moisture out and never give it a chance to corrode. Plus you get the added benefit of the plug wires detaching from the plugs fairly easily next time you change the plugs out ... Quote Link to comment Share on other sites More sharing options...
