The MAF was bad. Replaced the sensor and the code went away.

Sweet, glad ya got it fixed!

I found the MAF sensor is really sensitive, when I had MAF issues like I said I never got a code, but my MAF was bad enough to give me a misfire, and cause me to run really lean (10-16 STFT & 16-20 LTFT at idle), and it was only off of what it should have been at idle by around .10 to .15 lb/m it was reading .43 to around .50 lb/mat idle, when around .65 at idle was more of where it should have been.

I know many say K&N oiled air filters are fine to use, but after spending 160.00 for a new MAF I'm not putting a K&N air filter back in there, as I have been told by some that tune cars for a living that the filters are bad for cars with MAF'*, and I believe them.
I read that when your MAF mainly is effected is when humid, or humid+raining, as that helps the oil get to the MAF'* thermistors, as to how true that is I cannot say, I just know I'll stick to the best non oiled filters I can find from now on.

Sorry, meant to mention of course CAI intakes don't have the filter that close to the MAF, so they are said to not be effected as much, I still don't trust the K&N oiled air filters anymore..
I figure better safe than sorry/out of another 160.00

ive put k&n drop in'* in every vehicle ive owned, there have been quite a few. the only time i ever replaced a maf was because way back when my firebird still had the mpfi 2.8 i changed the ducting so it got the air from the bottom of the car with an elbow sort of like ram air. the first time i drove it in the rain it sucked up moisture and took out the maf. so its not the k&n or the oil, if you leave the stock ducting alone so you cant get moisture in there and dont go crazy with the oil it will be fine

I did use the filter for a few years before having problems, and I did clean it to no avail, it was still bad, so it is possible the MAF just was on its last leg already, I'm sure the thermistors do not have an infinite life expectancy, so it may have not been the oil on the filter.
I mainly choose to not put mine back in because right now if have another MAF fail I am screwed, as I am around 500.00 in the whole from car repairs already.

I do not have a CAI, but I did take my air-box out and gut the back side of it, I left the part past the filter/in between filter and MAF as it was stock, because I am pretty sure that along with the MAF screen help to keep the airflow straightened as if flows over the MAF'* thermistors.


I admit I may have over-oiled it once or twice, back then I did not know MAF'* could get contaminated with the oil if you overdo it, and I never cleaned the MAF because I did not know you are supposed to, so it could have partially been user error.

I may give the filter a try again in the future, I did not throw it away, I put it up in case I ever changed my mind, I paid too much for it to just toss it..

Hehe yeah it is.

The MAF was bad. Replaced with a brand new one, not a REMAN like what was in there. Lifetime warranty this time!

I have had a terrible time with remans. I put 4 on one car at work in one day that were remans. some were causing a rich condition and some were causing a lean condition. These were all AC Delco remans. On the 5th try i replaced it with a NEW one and it was good to go. I know i will never go with a reman on my personal vehicle. Anyways glad you got it fixed.
