Acura 3.2 TL is idling high and low while in park and stopped at a traffic light. Runs fine while driving. What could the problem be?

Probably an idle air control valve commonly called IAC valve. Its common. No check engine light though?

The check engine light did not come on. It only idles high and low sometimes because it hasn't done it since I sent the question in to you. Could a clogged fuel filter or trash in the throttle body cause this?

Thanks,

Unlikely to be fuel filter or throttle coz its intermittent. Could be a leak somewhere in the intake or throttle body. But you said it's fine now. Good luck
