Hi, DJC - check out some other posts -- 'Chugging / Bucking Cavalier' with my input and some others, "99 Chevy Cavalier Problems I'm Lost," and "96-98 Cavs seem to have the same problem." Are your problems similar to these? In my last post under "Chugging / Bucking Cavalier" - I am asking if this may be a safety issue since we have so many posts around this problem and views of our posts are really high (mine has had 228 views!). So ... should Chevy consider a recall of these cars since so many people are experiencing it and ace mechanics cannot figure out the problem?!?!? Anyway - wanted to see if yours was similar. Cathie

yes it is somewhat similiar thaks for the help i think there should be a recall on cavaliers

did u get cat check to see if it is plugged

WYG ... I'm car illiterate. Do you mean catalytic converter? If so, would an issue with that show up on the diagnostics or not? And it I ask my mechanic to check this out, am I looking at an additional big expense? Thanks for your expert advice! Cathie
