So lucky I just passed emissions. I've only had the 99 for a week or so--160k automatic 3.4 4x4. A couple of days later in traffic the light of death pops on and so it begins.

How are these three connected? I just finished reading scuba nightmare and mine is a little different. Truck runs fine. If I change out the MAF sensor will the other two fall into place or do I have to change out more sensors?

I know the 420 is probably the rear 02 sensor. How should I track down the 440? I haven't filled up with fuel in a week, but the last time I did for some reason the gas didn't stop and I think went out a vent line on top of the tank, not out the filler neck.
