but then i noticed that the check engine light hasn't come on at all. Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. So at first i assumed that the newer maf just doesn't work. rough idle for a second or two then it dies. The ECM controls the temperature of the hot film by a certain amount. Buy FAERSI Mass Air Flow Sensor Meter MAF 22680-7S000 AF101-2014 Altima & 2006-14 Maxima & 07-13 Sentra & 05-15 Xterra & 2003-2015 Murano. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). It measures the intake flow rate by measuring a part of the entire intake flow. (this is the same thing my old maf has been doing now) The Mass Air Flow (MAF) sensor is placed in the stream of the intake air. it does seem to clear all codes (no more check engine light and all codes seem to be gone) he says it should work.Ĭlear engine codes with ELM327 wifi odb2 scanner. I get used one from guy who wrote off his mini. And again, as a result, black smoke can occur easily. However, a malfunction of the MAF sensor can also overload the catalytic converter of a car. Incomplete combustion because the fuel and air mixture is too rich can result in thick black smoke. I tried to clean the maf out with maf cleaner. Black smoke is one of the 7 Symptoms of Mass Air Flow sensor. So i assuming as most would (i think) that its the mass air flow sensor. next day start it up take it for quick ride around the block. Solid argument if you ask me.So my mini starts stalling at red lights. Find aftermarket and OEM parts online or at a local store near you. On top of all the testing, K&N works with customers to make sure dealerships honor their warranties. Low prices on Air Flow Meter & Mass Air for your Infiniti G37 at Advance Auto Parts. My point being, I was ready to buy a K&N air filter. I work for an automotive company, but I'm not that into my car. The representative continued to explain the company's lengthy product testing process. Of the 2,500,000 filters K&N sells a year, they encounter less than 200 dealership problems annually. Where would all this "excess" oil come from? Hmmm. But I looked at the cone-shaped piece in the man's hands. Mechanics are telling customers that MAF readings show it is "saturated" with oil from the K&N filter. Is the filter fouling the MAF or is the MAF flawed? It is just as likely that the MAF comes defective from the factory. It is much more likely for oil from the engine to get sucked through the intake and foul the MAF. Do you know what is constantly cycling through the engine? You got it- oil. The MAF is fouled by oil right? Well, the MAF is in the engine. Even if you were driving 103mph and held a grease covered napkin out the window, the oil wouldn't come off-trust me. Mechanics are claiming that the oil from the filter is coming off the paper an affecting the MAF. The filter absorbs the oil, which coats it for protection, and is invisible. The napkin absorbs the grease, practically making the paper transparent. If you haven't, I will give you the low down. Have you ever gotten a really greasy piece of pizza and blotted it with a napkin. The paper, which is the filter, is coated in oil.
It attaches to a hose that brings air into the engine blocking dirt, bugs, and any other hazardous objects that happen to make their way under your hood. It is cone shaped part, basically constructed of a paper filter with wire mesh around it. If you are not familiar with what a K&N filter looks like, let me explain. The K&N representative, however, gave a compelling argument. What causes MAF problems? The dealerships claim excess oil from K&N filters is to blame. People around the country are bringing their cars to dealerships and mechanics with MAF(Mass Air Flow Sensor) problems. He even told us his life story- about growing up working on cars with his dad.īut, back to the debate. He loved his job and loved talking about auto air filters. Maybe it was the excitement in his words or the sweat dripping down his face, but I could tell he wasn't faking. But you know what? The guy knew what he was talking about. He stuttered and stammered over his words, as if it were his first presentation. Heck, he was as nervous as 6th grader giving a book report in front of the class. As I was sitting there in the K&N info session, listening to a bald man with a raspy voice throwing me his best pitch on air filters, I thought to myself, "K&N really does care for their customers."
