Question about 2005 Jeep Liberty
The OD lamp on most cars blink when there are errors.
what everyone does is plug in the scan tool and see the DTC codes.
my guess your finger trick fools the TCM .
for a while, and means nothing.
TCM are easy to fool ,its just a tiny microcomputer.
TCM is tranny shift brain.
why not connect the OBD2 scan tool to the DLC and see the Px7xxx codes spit out and then look them up in the FSM for how to diagnose them.
or get it fixed

I had the same exact problem and jeep looked at it over a dozen times. Jeep replaced the ignition switch and computer but they could never reproduce the problem, of course. I kept bothering Jeep until they replaced part of the wiring harness between the ignition switch the next conection. Problem solved. I had always said that it was a short in the wiring harness but they are too reliant on the in dash computer to tell them the problem. I hope this helps. P.S. this problem will kill your battery.

SOURCE: 4 wheel drive doesnt work.
Has this Jeep been modified at all?
It sounds like the shifter cable was reinstalled backwards.
Specifically the 4-Low "Not Climbing Well". 4-Low should give you the best torque and hill climbing ability.
Do you feel any "Binding" in the steering wheel (difficult to turn)?
Remember a Jeep uses real driveshafts and differentials to give you 4WD - you cannot engage 4WD or 4-Low on dry hard surfaces. It needs a little bit of slip between the wheels for turns.
Check you're fluids too.

Regardless of why the misfire is happening, the shop needs to find and make it right. If you don't return it to them, they can claim it's a new problem, unrelated to the work they did. As I don't have any idea if any sensors were imported with the new engine or if anything was damaged on install, I really can't comment past what I've said.
Hopefully you are dealing with a reputable competent shop...If so, aside from the obvious annoyance, they should definitely take care of the problem for you. I would check fluid levels to make sure that they are good and perhaps even check sensors to make sure they are all on securely but past that I would do nothing more. As far as driving, since you don't know what's wrong, I'd limit driving to only what's necessary but no more.
