I've got some weird issues with my truck. First, here's the details on the mod's on this truck:
It's a 99, 4.0, Auto, 2WD.
- 5.5" suspension lift
- 3" body lift
- 4:56 rear gears
- Jet Power Control Module
- K&N Intake (tube and filter)
- Dual chamber, 60 Series Flowmaster muffler
- 33 X 12.50 X 16 Mudterrain
Here's the issue(s). The truck has HORRIBLE gas mileage. When I first did the mod's, I did ALL of the mod's at the same time. All the mod details above were done during the same week, all before putting the truck on the road.
Before all of the mods, the truck was BONE STOCK, from the factory. It was getting roughly 15 MPG. After I did the mod's, it was getting roughly 13 MPG. That's of course thanks to the gears, intake, exhaust and Jet PCM. I've done a LOT of maintenance to this truck as well. Such as injectors, fuel pump, fuel pressure regulator, O2 sensors, MAFS, regular oil changes, tune ups, etc.
Today, I calculated that I'm getting only 8 MPG. Just a month ago, I did a motor flush, then an oil change, replaced the fuel filter and cleaned and re-oiled the K&N filter. Just 5 days ago, I did the spark plugs and wires cause the motor fouled 3 plugs.
Here's the kicker: The Check Engine light is on, as well! No matter what I do...no matter how much money I spend on this truck...that CEL STAY'S on! The codes that I pulled were P0172 (System Too Rich 'Bank 1'), P0175 (System Too Rich 'Bank 2'). The truck has had the CEL on for over 2 years now. Even after I replace SEVERAL components, that light is still on and with the same codes EVERY TIME: P0172 and P0175. WHAT THE HELL ELSE COULD BE CAUSING IT TO RUN RICH?!?!
If somebody can give me some tips as to what ELSE I can look at on this truck, I would really appreciate it.
Thank you!
