Ok, I've read about cleaning them for other trucks, but from what pics i"ve seen the sensors are a bit different than the one I have on my 04. I'm a bit unclear on which part(s) of it are ok to clean and what I need to not clean. I just don't want to ruin the thing. It looks a might expensive. Oh, and the "front two" O2 sensors... Are they the ones that are just before the CAT converter? From what I can tell there is one staring right at you and one on the tubing that's been bent up and over. One is pretty easy to get to and the other looks a bit challenging. Just want to make sure there's not one I'm not seeing. Thanks for any help.

 

Do a search on the MAF cleaning. It's easy. It is the first thing with a plug on top right side of the Throttle body. Two torx screws hold it in. You unplug it and pull it out. Do not touch the tiny sensor wire, just spray it withe the electrical cleaner. Put it back in and plug it up. Takes about 10 minutes.
