I understand that the engine idle is electronically controlled.
But lately when in gear the idle drops very low, in fact if AC
is on idle drops so low the entire steering column and wheel
vibrate furiously.

Does anyone know what parts in the system need to be checked
that advance and retard the idle, that could be the cause?

ive never had an automatic Honda, so idk if that has anything to do with it. but there is an idle adjuster screw somewhere on your throttle body. that's the first thing id check. if that doesn't help there are some other ways to adjust idle. but check the adjuster screw on the tb first and get back to us.

check ignition timing. also maybe clean the IACV. good luck

IACV = idle air control valve
