Steering wheel vibrates at idle when AC compressor kicks in. Smooths out under acceleration. No change in cooling either way.

If idle speed is dipping below 600 rpm, suspect a very dirty throttle plate/body. Clean carefully using throttle pedal w/ key on to open throttle plate (don't force open). Idle should be around 700-800 rpm.

If no improvement inspect motor mounts for problems.

good luck
