    when you were driving home did you go through any huge puddles? Just guessin, but could be your MAF got some moisture which caused the sensor to cool and give a false signal/reading.

    Just a suggestion...take out the MAF, clean it with MAF cleaner, install. reset the code

    no i din't hit any puddles but there was that huge storm so maybe i cleaned the sensor and it is stumbling a little. did notice that it was quite dirty so maybe i'll just put the old intake back on.

    Your not going to gain anything with an aftermarket intake without a tune.

    Even then, it's not really worth it.

    didn't put the intake on to gain anything did it cause it was free.

    yeah, it's kinda common to see that code if the MAF gets moisture

    Yeah...I now turn the car off all the time in the wash...even though I did for most of the time when I was in there and got the code. I also have the K&N filter cover/drycharger sleeve to cover it from moisture. I usually just take it back off a few hours later once all the moisture is out of there. Hasn't tossed a code at me since.
