Hi txgreasemonkey,

You helped me once before - thanks again! My current problem is rough vibration at an idle with a 93 Honda Accord. Motor is tuned and runs great. If you give car just a little gas and bump the rpms up around 800, it's smooth as silk. I replaced the rear, fluid filled motor/tranny mount about 2.5 years ago with an AutoZone aftermarket. I wondered if it could have anything to do with the idle air control valve. Can you offer any suggestions?

Thanks,
Jeff R Snellville, GA

. Clean throttle body.

. Clean air box and replace air filter.

. Adjust idle speed to 700 rpm, when engine is at normal operating temperature.
