The burn off can only deal with moderate deposits on the wire. A good MAF cleaner is always worth a try, don't use a contact cleaner as they have other additives.

Don't be too agressive with the wire, it's only 80micron diameter !

MAF cleaner has no acetone in it, unlike brake cleaner, so it is plastic-safe. Not sure about contact cleaner. Check the ingredient label.

That was my thought too, but the Ferrari's have the burn-off as well, made all the difference in the world on his car. SOOOoooo, Huh.... good to know.

Took my GTS in for it's annual emmisions test and it passed by the slimmest margin. The next year I used the CRC MAF cleaner and it passed with flying colors. Nothing else done with the engine during the year between checks. So yes it works!

So I am going to assume you just shoot it through the mesh screen

Used CRC MAF cleaner also.Did it on the car took the top screen out and put paper towels inside so it wouldn't go into the intake boot.Sprayed some then changed the towels and did it over again,instead of putting too much at a time and getting by the towels.Car started ok after.Used the small jewelers screw driver to pop the big clip to get the top screen out.

I have been used MAF cleaner with good results. Idle was much more stable and slightly better throttle response. The hotwire was dark before, but using whole bottle, it was clear again.
Used CRC brand and all of them are based on isopropanol, which is basically pure alcohol..
Contaminated hotwire cannot recognize minimal air flow or it's changes, therefore the cleaner helped for idle and low rpm throttle response.

Somewhere at 80'es we used to clean computer masstorge read/write heads using isopropanol, so it cannot harm the hotwire either

After cleaning the MAF you should diconnect the battery for an hour or so to reset the ECU, then drive the car to remap the settings.

I wouldn't mind doing this as part of my prep for spring. Is there any trick to removing the MAF?

Thanks

5 seconds are quite long enough...

"5 seconds are quite long enough..."

John,

I read that and nodded, then after I clicked on to the next thread a random thought intruded...

Suppose that an owner had a killer audio system installed, with an always-on power supply (yeah, poor practice) that had a few hellaciously big capacitors - given that we hope for 30 - 100 mA of current drain, how long would it take for the power to completely go away?

Randy V

I didn't see any of the 'experts' suggest it...

"Big Capacitors", if installed correctly, have a switched connection from source, and also have drain resistors for user safety. That said, I don't know many that are installed correctly in car audio systems. Most installers are focused, and have no consideration for the "what ifs" in electrical design. Like maximum fault current.
