Hi, I am John Mc, a Ford dealer tech. I hope I can help you quickly and accurately. One moment while I work on your problem.
This is a very common issue on these cars. It is caused by the camshaft sensor syncronizer. If you look directly down from the throttle body you will see the cam sensor on top of what looks like the bottom half of a distributor. This is the part that is making the noise. Replace that and it should solve your problem. As I said, very common.

Is this located under the where the idle air intake is? Thanks, Rob
This is actually attached to the top of the engine block. If you see where the accellerator cable is it is about 3 inches straight down.

I am soory I did not locate. this is laocated with two pin connector right beside the what appears to be vaccuum line.
It is straight down from the cables. You will see the spark plug wires and another wire harness. It will be directly under that.
Sorry if I wasn't clear. You need to replace the syncronizer under the sensor. This is what makes the noise.
