I installed an evolution intake in my 08 911S about a month ago and just had a check engine/visit workshop light pop up on my dash..I havnt had it checked yet, but im almost 100% sure its the mass flow sensor..

Is there anywhere i can buy the sensor online instead of going to the dealer?

Is there a different filter i can put on the evolution intake that wont mess up my filter?

 

I am running an EVO intake, and I don't have any problems with it. Did you oil it before the install? If so it might have a film on that needs to be cleaned. I would try that first.

 

No i did not oil it when i installed it, when i put it in it didnt feel like it was oily either..same thing happend to my mercedes when i put a k&n filter in it, so i figured it was the filter.

 

Odd, check your MAF, clean it and try it again. I would then try with replacing it.

 

Evo tells me they are now using a cotton gauze filter that can be used w/o oil. I wonder whether the few hp are worth the potential problems w cel and the long term effects of questionable filtration? So far I have resisted the temptation.

 

Most independent shops can scan the code for you for a nominal fee...

 

I experienced the same problem right after I installed my Evo intake. However, the CEL turned off after about 1 minute of idling. Make sure the connectors are on nice and snug.

 

I had no problem with my Evo. I have seen on posts that alot of people have a problem with kn

 

I checked it out and its reading " system running lean at idle bank 1 and bank 2"

Is that the MAF sensor?

 

I had the same problem with my K&N i had the mas Flow in backwards take a sec pull it out make sure the open part is facing toward were the air is coming in.it went right away once i faced it that way
