Well, at the Ford I work at, we use brake clean for MAFs all the time; in fact, that is all we use for them, just be sure to not touch the resistor as they break easily.For thethrottle bodies, Ford says not to clean them because they are not SUPPOSED to get dirty, but in reality, we all know they do. Clean them with brake clean and a stiff pipe cleaner...unless you wanna go the Ford way and purchase a new one. As far as the stalling at a stop off a freeway that is most likelya throttle body or IAC issue. NowI am not saying togo throw an IAC at it and it will be trouble free, but it is just a thought. And hammeron is correct on the vac lines about surging idle as well...

RE: Rough idle/ MAF Sensor Cleaning
As far as warranty work goes, we do not clean them we replace them. (If we cleaned them we would not get paid. Thats beside the point though.) Im guessing that ford thinks they shouldnot be cleaned...maybe just a way for themto make more money...anyway, we use BG brand brake cleaner...non-chlorinated if that makes a difference.Theoretically any volitle cleaner can be used as long as it does not leave a reisdue because that would effect the cooling of the wire during engine operation.

here's what you are refering to.

I haven't had to use it yet, however, I'm always skeptical about horsepower claims in an aerosol can! I can say that I have used their other electronic cleaners and they work well.

RE: Rough idle/ MAF Sensor Cleaning
I had a very similiar problem, the only difference is mine never died. The surging rpms really irked me, but I read on another mustang forum that the throttle body being dirty could cause the surge. I removed my TB, and it was VERY dirty with black stuff around the flange. I used some TB cleaner by CRC, and it fixed it. I have 33k miles and have been running a JLT intake for about 28k of those miles.

RE: Rough idle/ MAF Sensor Cleaning
UPDATE-Took off battery cable, waited 10 min put back on, no improvement.
Removed air hose from TB found blackish dust film or something on butterflies.
Tonight I will clean out theTB, filter, the air box and all the plumbing between the filter and TB, I hope this clears it up, otherwise I'moff to the dealership.
Any ideas to quickly dry a K&N filter after washing it, I know they say compressed air is a no no, but what about a hair dryer?

I ended up using my clothes dryer, when I got done washing the filter my wife had just started a load in the dryer.I grabbed a couple of paper towels and set the filter on them on top of the dryer. Dry in 1 hour.

RE: Rough idle/ MAF Sensor Cleaning
I set my filter on top of my A/C unit, it blows out nice hot air from the top.
