This is in my Pilot.
90% of the time, the car idles at a solid 750 RPM at a traffic light with all accessories off. But the other 10%, the idle dips to like 600-650. When this happens, the engine makes a rumbling noise and you can feel the center console shake a little. BUT...turn on the headlights or A/C, the idle rises and everything smooths out again. It's strange that this happens intermittently. Car drives great otherwise.
Any ideas what could be going on?
