The only thing I had done that could possibly caused this was oiling the filter - which I had assumed was a K&N type which needed oiling . WRONG !!!!!
I washed it out again - went for a drive and all was back to normal .

What surprised me was the fact that the restriction caused by the oil must have somehow thrown out the maf and caused the lean condition - that has me puzzled.
over oiling filters is a huge issue. many think more is better.

well less is more.

but it is better than a rag!

clean you maf,

put stock filter back in.. see what it does.

as to oil or not oil. read some stuff on the kn site on how to oil right. but really the kn does not need cleaning till 50k miles.

in between i just drop it on the ground. and run a leaf blower backward through it..

clean it lots oil it little.

hey,

i did not say it was going to be easy.. duh..

i have no idea what or where you intake goes or much less the filter trying to be used! but i would guess your car goes better than mine with a bad filter!

get rid of it--some of the k&n copycats are not a cotton weave filter but are paper made to look like cotton---bad when they are brand new for maf flow and if you mistakenly oil them --they become much worst. Stomp that damn thing for screwing your ride up and pray that KN will come in the mail.

/\ you could be right there . Would be really hard to replace though as it fits so perfectly . And my maf readings are so steady I would be loath to change it ....

Yeah - i'm pretty sure it does not flow enough but the location works very well . Given all the hassles ive seen on here getting a decent maf reading I think it may be the lesser of two evils .

There is a drawback to the filter in that location BTW . If it rains while the car is sitting water ends up dropping straight into the filter .
Driving in rain is fine - just when I stop is when I get that problem .
Need to work a way to divert the water elsewhere .

/\ ran a bead of silicone along the steel bumper mount to divert water away from the filter - seems to have worked well .

I can say catagorically that you DO NOT want to get water on your filter - it messes with the maf big time .

No $ for upgrades but the intercooler is the biggest barrier to more whp atm .
Im sure there is at least another 20whp in the turbo and the powerband is excellent so no point upgrading it .
