I keep throwing this p0101 mass airflow circut low I have changed the MAF 5 times with used good MAF's. changed the BARO. checked boost leaks and vac leaks. the only thing i can think is my BOV is leaking and the boost leak test shows its not. is it possible my air filter being oiled is causing the MAF to get oil on the sensor and causing it to go bad. any help would be great thanks
when you oil the filter do you put it right back on the car? because you're not supposed to put it on for like 24-48 hours to allow it to dry a little.

sorry u posted rite as i was adding to my original post lol. na i let it wick for like 45 minutes as per the instructions on the bottle. i apply it quite liberaly thow lol. this has been happening for a few weeks now my CEL burned out so i randomly scan it when i am at my shop and it always shows p0101. the idle is slightly rough like 50rpm rise and fall. and somtimes when i come to a light it drops from 900 to about 500 then goes back up.

Even well dried oiled filters will eventually contaminate the maf...just happened on my Tahoe two weeks ago. Cleaned the maf and away she went...
I have heard of people baking them in an oven (not used for food prep) at VERY low temps to help set the oil but I've not tried it...
