I've posted about my intermittent MAF sensor elsewhere but am wondering about what symptoms people are experiencing with a dirty or failing MAF sensor.

My 2004 was idling high, swinging from 1500 to 3000 RPM. Sitting at a light it'll be racing and revving making me look like a jerk. It'll idle down the road at 40 MPH. Braking and slowing will bring the idle speed down.

The only reason I suspected the MAF is that when this happened many months ago, the CEL came on and an auto parts store told me it was a MAF code (don't know which one).

The problem immediately went away for months.

After the problem came back a few weeks ago, I cleaned it with MAF cleaner and it immediately ran better.

Today it was revving higher and wilder than ever.

I'm planning to the MAF sensor tomorrow - BUT, I can't find a single description of MAF sensor problems that is similar to my symptoms.

Anybody else with this rev problem due to a MAF sensor?
