Car is hunting for idle

Car has started to have an up and down idle at stops. It can not seem to find a steady idle. I have a air fuel ratio meter and it fluctuates between yellow and red (yellow is nominal and red is lean) doesn't ever get into the green area. I pulled the o2 sensors and the left was whitish brown and the right o2 was a darker brownish red. What do you guys think. I tried to reset the computer and make it relearn itself to no avail. Thanks for the help

If the K&N isn't over oiled it doesn't cause problems. I have 3 cars with MAF's, running K&N's in all 3, never had a problem with the maf getting dirty.

I have had both K&N & Paper using paper now because the K&N neted me nothing on a dyno.
But it does not take much dirt flip out the maf.
Try cleaning the maf with a Q tip an clear achohol.
