Mr. MrCrowley, Thanks. I'll know better next time.

The dealer called me and found out that the air flow was lean. He said that they replaced a leaking gasket near by the manifold. It's under warranty and the total cost is $0.

I have a feeling that they looked further than just the O2 sensors problem codes. We'll see if they really took care of the problem. If not, I will buy a new MAF sensor and install it myself like DeerMagnet did.

Here are the details of the invoice of the $450 of last week.
