1996 GL, MAF cleaned at 65,000, now have 71,000 miles. Car runs great, but I just want to know suggested procedure for cleaning the MAF on the Zetec 4. Thanks, Chris

Just spray some Berryman B12 or non-chlorinated brake cleaner through the tube onto the wires to clean them of any oxidation and other contaminants. That's it.

Welcome aboard mate! Wow! Three newbie's in one day!  Well I take it that you did not clean yours the lasttime. All you have to do is pull it, spray it with carb cleaner, let it dry, reinstall. The best way to clean it is to actually remove your sensor from its mount. You do this by removing the two T-20 security bolts (need a special t-20 with a hole in the middle. Can get them at Autozone I believe) and spray the filaments with the carb cleaner and let them dry very well. Then reinstall it. You should not have to clean the MAF sensor that often, unless you have an open element or a K&N drop-in air filter that is over oiled. But you asked and I told ya! Have fun on the site.

Spray sensor with electrical parts cleaner (which leaves no residue as compared to some other cleaners).

This is NOT recommended (nor is it necessary). Not only are the sensor elements (thermistors) quite fragile, but the sensor is calibrated at the factory after it is installed on the housing. The MAF is one sensor that you want working at maximum accuracy, as the MAF readings are a major input on both fuel and spark.
Carb cleaner is also not the appropriate cleaner. Electronics cleaner or non-chlorinated brake cleaner (both already mentioned) are best for the job.

Actually, it was cleaned most satisfactorily by the garage that did it - I'm just a DIYer who wants to save a little $$ the next time it is needed.
regards,
Chris

I just changed my stock MAF (bought a ProFlow)..it was

at all.

I hope so! If it was dirty in there, then that's a big problem!
The wires accumulate oxidation (they are heated) and perhaps a little oil if you are using an open element filter or K&N. It will be hard to see, if at all.
