Lemme see I can find a pic of a 3.0L, but on my 4.0L, it's located under the engine cover, directly behind the throttle body, on the top.

I clean mine using CRC Mass Air Flow Sensor Cleaner. It's made for plastics and I could definately notice a differnece in running and gasmileage after I sprayed my MAF & IAC. IAC = Idle Air Control (i believe).

Look for something that looks like this...



If im not mistaken, on my old truck it as located on the top of the engine back near the firewall. Its been a while since i've had my 3.0, but just look for something like the pic.

It's located on the intake manifold near the throttle body. Looks just like the pic that was posted.

Clean your MAFS with some CRC MAFS Cleaner. I have never cleaned the throttle body so, no idea on that.
