logikf1ve Posted March 19, 2007 Report Share Posted March 19, 2007 About two weeks ago my '95 Lumina gets rearended and totalled by the insurance company, and yesterday this happens: I'm driving along the highway with my LTZ, I notice that when I was approaching the toll booths awhile back the car would have a random jumpy tach needle when idling in gear. I don't really think too much about it because I have had it do it before, so I continue on. About 15 minutes later on the way back I'm rolling about 70-75mph and I hear a CLANK and a WHZZZZZ sound. The car starts popping and misfiring pretty badly, though still running. By instinct I check the gauges and it's running normal temp at highway speed (around 140* or so) so I start to pull off to the side of the road and it stalls. I try to restart it and get nothing but incredibly hard cranks, occasionally it fires over but runs terrible w/o some gas pedal. Almost like it's running on 2-3 cylinders. Any ideas on what it may be? I'm thinking the timing chain jumped a tooth, just by the way its running. Given the car has 219,000 miles on it, I would say it had a fair run. Damn W-bodies! Oh well, guess I have another lawn ornament till spring or mid summer. Quote Link to comment Share on other sites More sharing options...

Turbo231 Posted March 19, 2007 Report Share Posted March 19, 2007 Do the basics first. Check for fuel pressure, check spark, check for things moving...easy to pop a sprocket cover and see if everything appears happy. Quote Link to comment Share on other sites More sharing options...
Canada Posted March 19, 2007 Report Share Posted March 19, 2007 Check compression, thats an easier way to see if the internals are okay. Quote Link to comment Share on other sites More sharing options...

logikf1ve Posted March 20, 2007 Author Report Share Posted March 20, 2007 I don't know what I was thinking but I didn't even think to check compression. I'll do some digging this weekend. Anyone know what normal compression is for a 3100? Quote Link to comment Share on other sites More sharing options...
