Hi!... I'm new to this forum and I am just looking around and reading what people are talking about, just so I can collect my own information. I was reading this forum, and I got to the last reply where "TrickyWhu" refers to the MAF sensor... Now, what is a MAF sensor?
Thanks for humoring me and I look forward to many more posts and replys from Land Rover enthusiasts! :D

A MAF sensor is hooked into the fresh air intake tube between the air filter and the Throttle body and is designed to measure the air flow as well as other factors so the ECU will manage the engine properly.

Mike,
Thanks again for the time you spent with me on the phone on Saturday. Your wealth of knowledge and tips are great.
I am ready to SeaFoam my 2002 Disco2 later this week or this weekend. To review, you told me to pull the vacuum line, get a length of hose, attach hose to vacuum port, let engine idle and suck in Sea Foam over a 2-3min period. Shut engine off immediately after SeaFoam has been sucked in and let sit for 30min.....correct???
Could you please identify which vacuum line I should pull?
Also, is there any reason to change the plugs after doing the SeaFoam?
Thanks again,
JeffQ

Take the MAF completely off the vehicle. Hold it horizontal, and spray through the inlet side with electrical contact cleaner (only). Then let it air dry for a few minutes and re-install it. DO NOT stick anything into it like a tooth brush or pipe cleaner, etc.
Geoman, how do you get it off? I found it and was able to get the pipe loose, yet the small pipe that it is stuck into won't come loose from the rubber tube (the terms used is the extend of my mechanical knowledge). I see two screws, they have a crazy star bit type pattern. Do I need a special screw driver for it?
I sprayed electrical contact cleaner on my wife's MAF Sensor (Ford Winstar) and it fixed the bogus codes (lean, etc). Having just installed new O2 sensors on my Disco, I pray that it will fix my issue too.
Any guidance is much appreciate. Man, I love this site. The knowledge here will help me regain the trust I was had in my '01 Disco.

Scott, Fords MAF's might take a cleaning but Rover's Bosch MAF's don't. The great % of them will fail when cleaned.
Do you have a check engine light on, what are the fault code numbers? if you don't have 2 lean fault code and a 3rd. gear shift fault don't touch your MAF cause there is nothing wrong with it.
