Gas mileage dropping faster than the stock market, less than 200 to the tank...

Here is more.

U sure someone is not syphoning your gas?

I'd be concerned about the cats. Nothing in the data seems to be out of place: fuel trims are good and the MAF value is good.

It would be interesting to see a graph of both upstream O2 sensor voltages to see how much and how quickly they're acting. Not sure if your scanner can do that, but it might be valuable data to have.

I got a locking gas cap...

I will try to see if it does. And definitely will look into the cats. Thank you!

I forgot to ask -- have you pulled a spark plug or two to see how they look? How many miles on them and how long ago where they changed?

when was the last time you tried tried to siphon gas out of one of these suvs?, my guess is it's been a long time because it's not gonna happen unless you take the the filler tube off from the gas tank
