I have a 2011 WRX and last night I changed my stock air filter (super dirty due to construction near work) with a K&N air filter and this morning when I turned my car on my check engine light was on and cruise control light was blinking...
I read in a bunch of threads that this could be due to oil from the K&N filter getting on the MAF sensor and that I should clean it.
However, the thing is while installing the air filter I was on the phone fighting with the GF and apparently I forgot to plug the little wire next to the air filter back in (is this the wire for the MAF sensor.... =(.... and only noticed it this morning when I but the hood to check what was wrong. I put the original filter back in and plugged the wire back in this time but the check engine/cruise control lights are still on... what should i do? I'm hesitant about cleaning the MAF sensor because of the people who said it can be easily broken....
thanks in advance guys
Should turn off when you shut the engine off and not come back on when you re-start it. If not take the battery wire off to re-set the ECU when you shut the engine off again and it shouldn't come back on again if that was the problem. (unplugged MAF sensor)...

Just put the k&n back in, make sure everything is pluged in, disconnect the negative side of the battery for a minute connect it back up and it will be fine.
As for cleaning the maf.. dude it takes a while driving on it to foul it up if it does at all. I've always been really careful with re-oiling mine and inspecting the maf every so often.. so far its not been fouled and I've got a good 48K mi running the K&N.
