Check Engine Code P0171
I installed a new K&N Intake 2 days ago, and just today my check engine light came on. I went to see what the code was and it says P0171. Anybody have any experience with this code or what I should do about it? I don't really know what to do!

It is not your K&N filter itself causing the problem, we have over 180K miles on test trucks (I have 50K on just mine) running K&Ns w/ no issue. If you over oil after a cleaning it can dirty up the MAF. I have heard, but not yet seen, that on occasion a new K&N filter may have caused oil fowling to the MAF because it had too much oil when made. Might be an urban legend?
Can't say the same for the K&N warm air intake. The CEL can be cause by how it was installed (ie. like a leak where the MAF is re-installed) or any hairline crack in the plastic versions.

-Or-
You can do what a lot of others have, take the K&N intake off, put the OEM back and see what happens. If the CEL stays off, you know what was throwing the CEL. Somebody around here did that, called K&N and they authorized a return of the intake? If they won't, Ebay it.
Honestly, there is nor reason for the K&N intake in and of itself to throw the code, it usually boils down to a minor installation error, but not always.
Then, get a different intake that doesn't cause that issue.
