IDLE AIR CONTROL VALVE

2001 Mercury Marquis • V8 Automatic • 155,000 miles

I have an 01 grand marquis that started to make a high speed vibration right by the idle air control valve. I could rev it up to make it go away but it has gotten worse. Is it the valve?

Try cleaning out the idle air control valve and see what happens
