gmrulz4u Posted December 23, 2004 Report Share Posted December 23, 2004 It's been about 8 months now since anything has gone wrong with my 89 Cutlass Supreme. I was starting to like not having to repair or replace, and instead just maintain! But lastnight I drove to Mississauga, Ontario to pick-up my brother. It's an hour and a half drive on the highway. Going there, everything was smooth as always. But, on the way back, about 20 minutes from home, I noticed quite a violent shaking and vibration through the gas pedal, floor board, and especially steering wheel/column. For some reason I thought right away that it was a transmission thing, but then I realized it was doing it in every gear, and ONLY when I was at a certain throttle point. For example, if I was 0-20% on the throttle, it was fine, 20-50%, it was shaking violently and wouldn't accelerate, and 50%+, it was fine!?? It was also making loud, almost grinding noises. And the steering wheel shaking could be heard as well as fealt. Same with the gas pedal itself, I could feel it pulsating really violently in my foot. Needless to say I was very worried. Once I got onto city streets, I noticed it would even do it in 1st gear while starting to accelerate initially, then once I got past the throttle point in which it woud shake and rattle, it would stop until I was in the next gear and back at that same throttle point. It kind of felt to me like something was all-of-a-sudden very loose, like something in the steering rack, column, or drive-line. My brother is under the impression that it didn't start doing this until I had accidently drove over too far on the left hand side and ran over all those closely placed BUMPY things to make you slow down. But I am not sure this is the case... Anyways, what makes this SO strange, is that once I got off the highway and to my parents house, I shut the car off, parked it, and went inside for about 20 minutes. Then, when I went to leave to go home, I noticed that the shaking and vibrating was completely GONE!!!! What the hell!!?? Simply shutting the car off and parking it for 20 minutes has somehow cured the problem!!?? I drove all lastnight and so-far today and it has not done the same thing once! Not even a little bit! So this has me totally flabergasted. Because I could see if it were an engine problem, then maybe reseting the engine by turning it off could possibly fix it, but this in no way felt like an engine problem at all! It felt completely like something was phyically damaged or disturbed. Maybe I'm wrong? I mean, I know when an engine has a mis-fire like a bad coil that the engine will shake violently under load, so maybe this is the case, but it definately didn't feel like it to me... Anyone have any input to this crazy story?? THANKS GUYS! Merry X-mas Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 23, 2004 Report Share Posted December 23, 2004 Long time no see! If it happens again, have a spark tester ready and see if s a few cylinders aren't getting spark. Thats my first guess. Quote Link to comment Share on other sites More sharing options...
gmrulz4u Posted December 23, 2004 Author Report Share Posted December 23, 2004 Long time no see! Yeah, you're telling me! I missed you guys:( I just a lot of other stuff going on for the past 6 months or so...time goes too fast... But thanks for the input Brian! So you just think it was an engine / ignition thing? Have you ever heard of it happening so badly that it literally feels like something is really loose, the steering wheel is shaking so badly that I can't keep it from moving etc...?
