Clean your MAF!
I just cleaned my MAF - got the crud out and gave the wires a good spray down with MAF cleaner. What a difference! . Feels like I picked up 50 hp 
There was a bunch of grit and stuff blocking the screen and what looked like a small twig!
I dumped the K&N last Christmas and am running with stock paper now, don't know if K&N oil had anything to do with it, but this is an *easy* bit of maintenance that gave results. It's probably why ppl think they're getting extra hp from so-called performance MAFS - their stock ones were probably just dirty

That sounds like a good thing to do,but I have not tried it because that wire the size of a human hair,and a red one at that,scares the hell out of me.I'm afraid to get anything near it,even a spray cleaner.Is that wire tougher then it looks?
Well I see you have a newer car,mine's an 86.I'm sure it must be different.

By design, it shouldn't be a maintenance issue - most work or they don't. Would like to see your BLM's before and after the cleaning - if it wasn't working, it's usually Rich/Lean. For those with a Scanner - scan it and see.

IMO the K&N is crap. Yes it will let in more air thus giving you more power, but it lets in more crap at the same time. I lose 2 MAF sensors because of them. Never had a problem with paper filters.

The K&N filter oil can be a real problem if you get carried away.
I would clean the MAF sensor on an annual basis. I would change the O2 sensor if my Corvette has over 75,000 miles. These two things will do wonders for your idle.
Beside you won't be spending a lot of money and both give you an excuse to hang out in the garage for a few hours.

Clean your MAF!
I agree. Mine was running real rough with lots of hesitation when hitting the pedal. The Chevy mechanic cleaned the MAF and told me to get rid of the K&N filters (I had the SLP triple intake which has the 3 small round K&N filters). He said it inhales too much oil from the filters. Then more particles & stuff stick to the sensor. I changed back to the stock dry filter and it ran fine and never had the problem again.

Cleaning is a smart one however.
