Any performace changes now that the light's on? If so I would check these two possiblities.
I took off the top of the air cleaner housing last night when I was changing the light bulbs. I disconnected it on the first clamp on the air box side. I did not disconnect the MAF sensor. I could have dumped something out of place. It is on snug but is possible that it is not on perfectly.

Yes it doesn't seam to be running the same and it actually stalled at a stop light. Not a big deal but it did take me 10 seconds to realize that I couldn't restart it because it was still in drive. Damn automatics.

AutoZone checked the code. It is reading low input from the MAF sensor. They said it happens a lot. He sold me some electronics cleaner and said to remove the MAFS and clean it out really good. He then suggested that I take an air compressor and blow out the K&N to remove excess oil from the filter. Although I didn't oil it, it came preoiled.

I'm going to try this after work.
