Hey Everyone!

I just bought a 91 Celica GT, auto. My problem is at idle around 1000rpm's car shakes, more like a rumble, and when im driving past 100 on the hwy it gets loud. Could it be a pluged cat? Any sugestions would be great!

Anyone have any ideas?

motor mount? Why do you need to go past 100? Possibliy a tranny mount.

So you can pass people, duh. Motor and tranny mounts are fine, just seems really loud.

what about the exhaust system. If jou just rev the car to the rpms (while sitting) that you are turning at 100+, does it still rumble. If it does then I would look at the exhaust system and possibly the timing. But I don't think it would be the timing.

Yeah its something to do with the rmps when its hot and under 600rmps its quite but as soon as it sees 1000+ gets a lil noisier, i think it might be the timing...
