Use brake/electrical parts cleaner.

so, what, are you saying to 'swish' the thing around in a large Ziploc bag filled half way w/ the stuff? or should it be dipped in a small bucket of the stuff and gently go back and forth allowing the cleaner to flow through the matrixes - your opinon pls - thx

I wouldn't dip your MAF into any kind of solution unless you want to be buying another one! Go to Advance or AutoZone they make a MAF Cleaners that comes in a gray spray can! Just follow cleaning instructions!

Thanx!

Key word is GENTLY or DELICATE (FRAGILE?) A single 'blast'from a spray can tube can break the fine wires. I would be surprised if the sensor wires are dirty. There is an automatic 'burn clean' electrical pluse sent every shutdown.

Does it matter if it's the electrical parts cleaner or the electrical connection cleaner? I bought the quick dry connector type cleaner.

agree,should not need cleaning if always used factory filter- mine has never been cleaned in the 179,000 miles it has had air pass through it.

When you are accelerating 3/4 to WOT the MAF accuracy is critical as it over rides everything to tell ecu the amount of air and thus the fuel requirements.

Since you could be at 10,000 feet or below sealevel, the air density could vary 30%........the same with hotter than 70F air yielding another 5%.

Temperatures usually drop 3F per 1,000 feet.

Since WOT is excessively richer than 12.2 AF to cool the pistons say 10-11AF an error of not measuring [reporting] enough air is the same as thinner or hotter air.............10% lean error will lean the 10AF fuel to 11AF, 11AF to 12.1 AF etc etc.

When you have a stock ecu there is safety built in for error, however a reprogrammed power ecu will have no [little] reserve for MAF error! Since the stock 10-11AF has already been leaned to 12AF.

Reprogrammed ecu have an added maintenance requirement to maintain a very accurate MAF!..........otherwise the mixture could get extremely lean [leaner than 12.5:1AF] and raise the combustion temperature causing KS activation and reduced power output..........and possible damage if you stayed WOT for more than a few seconds.

Unlikely but it could happen.

Sensor #5 is close to 90-96Q MAF..............+4.33 volts =1000kg per hour =277grams per second or roughly enough air for 320-325 HP [if fuel and BMEP can cause enough pressure]
