I made the mistake of unscrewing those two screws on my MAF sensor yesterday. I thought I got TB cleaner in the air vane, so I was going to remove it to blow it out. Once you take off the two screws on the top of the air box, you pull and tear out all the soldering that the computer needs to communicate with the MAF sensor. Then your car wont start and a rebuilt part is $160.



If it werent for this forum, I probably would have had to buy another part. I soldered it back and the truck runs great now- Seafomed the plenum, cleaned the throttle body, advanced the timing a bit, and had to change the plugs because all that crap that broke loose made them look like this:



Gotta love changing those plugs on the 3.0
