Yea John im going to try this out ASAP< im just not familiar with these engine's, maf sensors and so on and dont want to mess anything up, i know im a little too cautious i guess, but very capable of doing it lol

 

It's a simple job and if it doesn't fix your problem, you can steer away from the MAF as being the cause of your problems and then lean towards the plugs as being the possible issue. It's just steps in simple troubleshooting...

 

Good point, yea i noticed tonight it wasnt because the car was sitting with little gas for a while, i put dry gas in the tank on 2 gas stops and didnt cure the issue, it still sputters through boost then starts kicking hard, sort of like its losing traction but it isnt , thanks

 

Make sure you but the correct cleaner pictured at the beggining of this thread. The goob at auto zone showed me something real similar BUT as I read the can it said do not get on plastic. The stuff at the beginning of this thread is what you want. They did have the correct stuff at auto zone but it was in a little spray can with the red nozzle. Worked great but my car was not exhibiting any trouble before hand. I just figures it could not hurt sinc e I had a BMC filter in it for a while.

 

Ok man thanks a lot, I will definitely make sure I get the correct cleaner I'm going to do it tomorrow ..

 

should i disconnect the battery first? and before cleaning it, did you see any residue on it? or will that stuff be invisible to the naked eye?

Im gonna do it on the m3 too...

its probably the plugs..... replace with bosch fr6 and NOT the berus

 

Yea im also going to change the plugs, i want it fresh

 

tell me about it...running those french craps and i believe that they are the cause of hi load load sputter. the car in 4 5 6 gear sputters hard @ 4.7 to redline. ill screw in some plugs and clean the maf.....

hi load sound like plugs doesnt it?

 

Same company actually makes something called the MAF Cleaner.

Did the same thing with mine. I actually went through almost the whole can. Cheap alternative to buy a new MAF..

To bad I thought it didnt work and bought a new one anyway. lol.

 

So can a dirty MAF cause a misfire code? Maybe this will work; because I'm not noticing any hesitation (I have a lead foot though). I'm a newbie so be nice .

 

For $5 you can try lol.

 

Pardon my newbieness , but the the MAF screws have a star-like pattern right (meant for the torx socket)?

 

you need security torx...
what you need for MAF DIY

 

I cleaned my MAF, and its like Dock said... Its amazing how much different my car accelerates now. No hesitation in the 2,800-3,000 rpm range and its a lot smoother running.
Thanks for the right up.
