engine vibration HELP PLEASE!!!
About two weeks ago my CD7 SE(F22b2) developed an engine vibration just out of the blue.
It shakes at idle but if i bring the RPM's to about 900 the vibration stops. it feels like my car is a giant back massager. I checked the engine mounts and they checked out good, so I replaced the spark plugs, distributor cap, PCV valve and washed out my AEM dryflow filter and it did not help, what do you guys think is wrong? thanx!

what rpm does it idle at now? should be around 750 and you may need to adjust it.

i would take a real close look at the rear mount ,, also make sure that there is vacc at the mount diaphram when engine RPM is below 700,,, I am assuming car is AT .

I have a 2000 LX, and it developed a rattling/vibrational sound when it would idle and when I decelerated while going at a slow speed. Turns out my catalytic converter went bad. I spent a small fortune getting it replaced and it fixed the problem, but man....that cat con was expensive as hell!

Hen_Rock, had a similar issue. My cat would have a really tinny sounding rattle at idle and deceleration and I just removed the lower heat shield on it and it went away. What could it have hurt? It was only shielding the pavement.
