Where is the MAF? Is it the sensor in the air filter compartment? I don't have my Haynes' manual handy to check.

The car is back at the Ford dealer for the second time now. They replaced the serp. belt and idler pulley on Wednesday to the tune of $190US, but the sound is still there. Now its up to them to fix the problem at their expense.
