Hi,

New to the jeep club.

I have a 2006 Jeep Liberty CRD 2.8 L Diesel, EcoTune, with deleted cat, straight pipe, EGR deleted, K&N Air Intake.
I do a lot of towing with this thing, and never had a loss of power problem.
Just went over 200,000 miles, on the odometer. Driving today notices that when I pressed the accelerator pedal down, the RPM was stuck at 3,000 without any movement, or power for acceleration.
I also noted at times, my each light on the dash lights up at once, then goes off. I am thinking something is off with the tune now.

Any experts on these tunes in Ohio?

Thank you in advance,

It is unlikely that something is wrong with the tune. If the ECM goes bad, it is usually an instantaneous no-run situation, not a series of "glitches" like a personal computer.

I would start by having both the alternator and battery tested by a decent shop. A failing battery or one that is consistently running low voltage due to a bad alternator can cause all kinds of electrical issues and put the motor into limp mode (what your loss-of-power sounds like).
