*Read* Clean Your MAF Sensor for Smoother Idle Yes, Your MAF can get dirty from the oil on a K/N air filter. I would always over oil the filter and as weeks would go by dirt would build and mine idle would get roughter and could really lean out the car. Those little sensors read the incoming air coming in from the filter and then tell the computer how much fuel to deliver to the engine which could be lean or rich. I know what I am talking about, cause I dynoed mine before being dirty MAF then After clean MAF..( from 13.5 Air fuel ratio to 12.5 air fuel ratio) a whole point. Granted everything else was up to date clean injectors, plugs fuel filter etc. When cleaning, you can use MAF cleaner at auto store or I used rubbing alcohol with q-tip. Be very careful not to damage those little sensors or you will have to get a new MAF Just disassemble the MAF from air lid, then MAF housing until u have the MAF Sensor. AGAIN BE VERY CARE FUL NOT TO DAMAGE THOSE LITTLE WIRES INSIDE. When all other maintenance is done new plus clean fuel injectors, fuel filter etc this will make a diffrence in your idle. Mine was smooth no more up and down idle during cold start ups. Cleaning your MAF can also help richen your Air fuel Ratio by a whole point. I hope this helps you guys who are having Idle problems and A/F ratio problems. |
i would also like to add, i had an odd problem where driving 1/2 throttle or less, the car would "stumble" and lose power a bit between 2k-3k, once i cleaned the maf it runs perfect again. dont overlook the easy stuff! |
How do you clean your maf? like what do you use? |

Check out CRC Chemicals Mass Air Flow Sensor Cleaner, they sell it at most auto parts stores. It's designed specifically for cleaning MAFs, as you could probably guess by the name. It's what I use and seems to work fine. |
^ Same here, I always use the CRC. . . . It's like choke cleaner, but leaves no resedue. |
such a ridiculous thread you admitted over oiling filter well what do u expect |
:eyes: even regular amounts of oil on your K&N can cause this. If you dont have anything constructive, don't post... |
Many don't know that you're only supposed to oil the BOTTOM of the K&N. It'll soak through fine. Make sure you let it dry for at least 4-5 hours before running the car again. I've never had a problem after reoiling my K&N, even when giving the top a very thin coating of oil. |
stock mass air fuel pic Hey I was wondering if anybody had a picture of a stock 2000 z28 mass air fuel assembly, or if you knew where I could see one |
Not to start a shit storm, because I don't argue this point amymore.....but why don't you K&N users give up that ridiculous K&N filter, give up that .01 hp you think you're picking up from using it because it allows more air flow, which means more DIRT into your engine...which means more ring wear every time you drive your car.....and just use paper filters. And hey, never a dirty MAF from that oil crap on the filter. :chug: |
Not to start a shit storm, because I don't argue this point amymore sounds like you do still argue the point. |

I've K&N FIPK, gee I guess a paper filter won't work! :bang: I've used K&N for longer than most here have owned their cars or been alive, K&N filters work period! I have never had a MAF get dirty to the point it effects performance. No you don't soak them in oil!!! :bang: |
Problem is, most people with a K&N clean it to frequently. Also most do think the more oil the better. They actually work best when they are dirty. Not packed with crud, but they don't need cleaned every 1000 miles either. A light coat of oil is plenty. I always let mine set overnight as well. Mine has been on my car since 01'. I clean it about every 6 months. It's already paid for itself and i've never had a maf problem. Most of the time it's user error... |
