How do you clean a MAF sensor?
Lately my car has begun to intermittently stumble. It has never done that before. At first I thought it was gas, but now it has started to do it again (very infrequently) 25% of the way into a new tankful from a different filling station. I thought it may be an intake leak, or more likely, a dirty MAF. I have seen this on the forum before, but cannot remember what was suggested to spray on the MAF wires. I know we're not supposed to touch them. If I pour rubbing alcohol on them, after removing the MAF from the car of course, will that do the trick? Thanks!

I use spray brake cleaner. The good CFC stuff if you can find it, not the green stuff. I have also used Gumout spray carburetor cleaner.
I always remove it for cleaning, I would not want the cleaner to get in my engine.

I use carb cleaner. But be careful if you use Nylon MAF ends. It could eat at the plastic.

Re: How do you clean a MAF sensor? (Nilla Ice)
I've used rubbing alcohol and a Q-tip and found that works fine. The last time I did it, I wanted to use something a bit more "inert" than alcohol or carb cleaner as I was afraid of a possible chemical reaction between that and the MAF wires. Since the MAF wires see water all the time in the air, I just cleaned mine with a wet Q-tip figuring that water certainly can't hurt it. It took a lot of stuff off and worked fine. Just be VERY gentle!

Freon would be the best! Too bad it's pretty much outlawed. The PC industry used it to clean PCAs for several years....left no residue and cleans some seriously sticky flux

Agreed, you know the "Canned Air" still may be a very good choice - although it isnt freeon based - but it still gets in all the cracks and corners qtips wont go .. humm....
