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.

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.
