My '90 Corolla DX has vibration. The vibration becomes noticeable only at stop (gear "D") when AC is on & engine warming up and temp going up than without AC on. If i shift to gear "N" or "P", then vibration dies down. No vibration with normal temp. engine and everything o.k. what goes wrong? Matt

I've been running 87 octane for a few weeks in my Celica. I am going out of town this weekend, so I filled up with 93.
For the past couple weeks, i've had a solid engine mount on the driver's side, to which I've incorrectly attributed all the vibration -- my car seems to notice a difference between 87 and 93 and vibrates *less* at idle with
Just one person's observation.
You forgot to mention checking for Mexican jumping beans in the glovebox.

This question has been addressed sooooo many times. Check the idle speed with the A/C turned ON. Must not be below 700 rpm in DRIVE. It if is, the normal engine shake will worsen. There is an "idle up" diaphram on the intake manifold that is adjustable .... providing it is operative.
