MAF Cleaning
I installed a cold air intake from Jaguar XP and got an engine fault code/poor engine performance on the second day. I suspect the MAF is fouled, and want to clean the sensor.
I've searched forums for cleaning guidance, but the search engine doesn't like short words like "MAF," so I haven't been able to locate any instructions.
Anyone direct me to the procedure?
BTW, I'm not positive that's what the problem is - I'm taking to my mechanic to get the codes.
Thanks!

I have a pdf of the procedure with pictures that I downloaded from another website that I can email you. Or you can visit the website which is maxperformancecars.com and find the article. It is really very simple. Unscrew the MAF from the intake, spray in some MAF cleaner, reinstall. Takes all of maybe 5 minutes.

Happy that you found the article. The most frustrating thing about the throttle body cleaning is the location of the TB. Moreover, if you climb onto the engine and site down the TB, you will see that the location of most of the gunk (by far) is actually below the throttle body at the base of the manifold. It is virtually impossible to get something down there to clean up that gunk.

Update
Upon disassembling the air intake, I discovered the MAFS on my '97 is substantially different than the one pictured in referenced article. To access the wires, you have to squirt the cleaning fluid through nozzle in the center of the assembly (if you have one, you'll know what I'm talking about). I suggest spraying the fluid from well outside the nozzle to avoid potential damage to the sensor wires. Then, let it drain/dry onto a clean towel.
After scrubbing and scrubbing the intake tube, I still had sticky, gooey residue when I had a brain storm. The MAFS cleaner is plastic safe, so I squirted a fair amount onto the goo, then scrubbed. Works great.
I finally bought a OBD code reader and got several fault codes all relating to the MAFS, confirming my suspicions. After everything is bone dry and I've cleared the codes, I'll reassemble and see what happens. I'll probably reinstall the factory air box, too.
