I had never cleaned my MAF sensor before, but my car was taking forever to accelerate, putting me in danger on a daily basis. I pulled out the MAF sensor and couldn't even see the two wires that were supposed to be there, because they were encased in gunk. A few quick sprays with this cleaner and the gunk was gone, leaving two shiny wires behind. Immediately after that, my car was accelerating like it was brand new.

Bottom line is, if your car feels like it isn't getting any gas, try this cleaner on your MAF sensor before handing the keys to a mechanic. It's easy as can be...anyone can do it, and it only costs a few bucks. If it doesn't fix the problem, big deal. At least your sensor is clean, and the risk is minimal considering the potential reward.

I bought a 1999 monte carlo (V6, 3.1L) last year with just over 120k miles on it, it ran... pretty good... most of the time... but occasionally it would stall or bog down at times. No matter, I paid peanuts for it, it has a nice warm heater, cold A/C, dreamy ride, and loud stereo, so I was happy. You can't win them all...

Well, the most recent time it bogged down I was going uphill on the interstate and it bogged down for a bit, but this time, the engine light came on. Ah-ha! A clue! I said... I took the car up to smyth automotive and had them read the code, which was P0101 (MAF circuit, range or performance problem).

I took the car home and sure enough it was putting out maybe 15 Hz at idle, 28 Hz at 3500 rpm. (you need an oscilloscope or frequency counter to measure the output with the GM sensor, should be much higher apparently, maybe 35-80 Hz). I contemplated getting a new MAF sensor but saw this product and thought why not try it? After the cleaning, as soon as I turned the key, the engine light went out. Performance was just like a new car! I floored it, and my head was thrust into the headrest 'with gusto' ;) as the speedo approached scary numbers rather quickly.

I showed the product to my dad and we tried it on his 1999 suburban 5.7, which has had the engine light on for years (has close to 300k miles now)... a decent improvment there as well.

Bottom line is, if your car is due for a new MAF sensor you really ought to try this stuff, remember it is a delicate and precise instrument so handle accordingly! Please do not try brake cleaner, isopropanol, simplegreen, or whatever else you might read about on the internet. (you know, the "trust me, I'm an engineer" crowd). Spend the $5 and get on with it.

This is still a relatively new product and is it seems like it is just starting to hit the tuner/hotrod scene (those high-zoot "oiled filters" can have potentially disastrous results on a MAF sensor!)

My 2003 GMC Sierra 1500 HD 6.0L threw a P0101 Mass or Volume Air Flow Circuit Range/Performance Problem diagnostic trouble code. It did not show the check engine light, but my cruise control stopped working, so I scanned for codes and saw the P0101 DTC. I used this cleaner, which took about 15 minutes, and then cleared the code. My cruise control has worked fine ever since.

We have a 2002 Nissan Pathfinder that started throwing the Check Engine Light. After using a cheapo ODBII scanner, we found a few codes that pointed at several different things. Strange thing though, we never got multiple codes at the same time. I'd reset the car computer with the scanner and then we'd get one code for a swirl sensor problem then we'd get another code the next time for a oxygen sensor and then we'd also sometimes get a code the ODBII sensor had no idea what it was (probably a manufacturer specific code that wasn't in the scanner's database). I first replaced the o2 sensor since it seemed to be the code most often thrown and also since it's a common issue with the Pathfinder. That seemed to get rid of the CEL initially. Then the light came back on. After considering whether or not we should just replace the swirl control valve (another common issue with this car), I came across a posting somewhere that the Mass Air Flow sensor could be the culprit to all these other codes getting thrown. Replacing the MAF sensor itself is kinda expensive, especially if you go the OEM route. So for kicks, I decided to give this thing a try.

First off, this thing is really easy to use. It's almost like spraying pressurized water. Now it's very hazardous stuff, so use caution. This cleaner dries super quick. Once the sensor was cleaned and dried, I put it back in, reset the car's computer, and crossed my fingers. About 600 miles later, the check engine light has not come back on. I'm hopeful since prior to using this product, the light would come on after about 30 highway miles.

If you're having a check engine issue and an ODBII scanner is showing some codes associated with the exhaust and airflow check systems, definitely try this out.

I used this on my 1995 Subaru Legacy. As far as I know the air flow sensor had never been cleaned. The difference was noticeable, the engine ran more smoothly and acceleration was much better. The old Subaru ran like a new car again. I highly recommend this product.

Do yourself a HUGE favor and use a mass flow (MAF) senor cleaner to clean the MAF sensor. DON'T use carburetor, fuel injector or throttle body cleaner or you'll ruin the MAF sensor.
