Ok, let's go back to the tires. Are they P-Metrics or LT tires on their now? If LT and you're running the air pressure the same as door sticker you're under-inflated (unless your door sticker is for an LT tire, not a P-Metric).
Did you run those little bottles of Super-Tech yet?
If all else is well I'd start eyeballing those cats. Changed mine and my mileage is finally back up to near where it was when I bought it and getting better. Haven't been driving it lately due to back pain though so no updates on its mpg journey.
AT terrains and the pressure was around 42 i think when i checked it. i ran BGK44 and that Berrymans stuff. how do i check the cats? the temp of the pipes before and after the cat after driving?
