2004 TJ
4.0 Inline 6
3.73 Gears
35" Tires
5 Speed
Now that the tech specs are out of the way. I have noticed a severe loss of power on acceleration. This is not due to the Tire / Gear ratio. I have been running this setup for a year. This loss of power is more of a bogging down when you open up the throttle.
If I am light on the throttle engine runs and sounds fine. If I am heavy on the throttle there is a drop in acceleration and the engine sounds like it is starving for fuel. It will do this under load and under no load. The best way to describe the sound is low and throaty. I do not have a check engine light and I am not throwing any codes.
1. Poor fuel delivery - fuel pump or clogged fuel filter.
2. Poor air delivery- I doubt this one
3. Poor exhaust flow - Might be (I hope not as I have the three cat setup)
Any other ideas besides this?
