It seems that you may have a wiring problem. When you put the car in reverse the engine will twist counterclockwise and could be pulling on a harness.
Start the car and move or jiggle harnesses under the hood and see if the Jeep acts funny. If the Jeep hiccups while moving a harness, you've narrowed down the area where the problem is.

Jeep Liberty 2004 error code P0144

Code is "Oxygen sensor input voltage maintained above normal operating range"

Very likely it's the Lambda sensor on the eshaust playing up. Check connections and get it tested.

Can give up with faulty fuel from some pumps.

My '99 Volkswagen Jetta Wolfsburg edition is having some problems, i have irregular idle speeds. For example when i am idling it will be normal and then almost hiccup where it will drop idle speed and then...

I would say don't replace anything until you have the "fault codes" read via the on-board diagnostic system.

Hope this helps. If this "fixes ya", I'd appreciate a rating for my reply, If not, please delay the rating and add a comment with any extra info you have and I will try to think of something else.

Cheers, D.
