My car engine sometimes starts racing when it's idling or going slow. on 1997 Ford Taurus

Intermittently not constantly, car engine starts racing when I'm at a traffic light or drive-through. I have to stomp on the brake to stop it from hitting the car in front of me. It happens off and on, sometimes not at all for weeks, sometimes 2-3 times in the same short trip.

It sounds like the idle air control motor may be going bad

Thanks for the tip, but when I looked up info about this online, it sounds like it leads to the engine stalling out, not racing.
