Hey crew,
So, the 2002 Liberty (which I just put some money into) may have finally given up the ghost. I will take it to a mechanic Monday to see if I can learn more.... but this forum may know more than everyone.
Here's the story. :favorites68::favorites68::favorites68:
The 02 Liberty Limited (3.7 V6 Gas) has 185K miles on it. It has been running great. There have been a few times in the past when it started and the idle seemed off, really rough at start. I'd goose it and it would find its grove. It seemed like it did this when I started it fast and was shifting while starting it (I'm exaggerating, but stating I was in a hurry). It has never been a problem.
Today, I drove to mom's... parked it. When leaving, started it and it was bad. I heard distinct ticking, and it seemed like it was running on 4 or 5 of the 6 cylinders. I was also low on fuel. I got it started by presing the gas pedal, eventually.
I made it to the auto-parts store and bought some oil (it was very low), and some Lucas fuel cleaner and lucas oil treatment (hoping). Oh, and I also got a tank of gas prior to adding the fuel cleaner. (Well, I added just a bit before I got my gas and then added the rest after 15.5 gallons). I also had them pull codes. The codes came back P0120 and 13 (according to the guy who I think had a high school education...)
Now, it is running, but will no idle and there is some smoke coming from the exhaust. (I honestly can't tell if it is smoke or un-burnt fuel?)
If I am coming to the stop light I have to put it into neutral and keep a little gas on to keep it somewhat idling. I do think its probably oil... (the ticking when I first started it at Mom's... sounded 'valvy' to me.)
Although there is no ticking now that I can hear. It is running rough and doesn't really idle when coming down from normal rpms.
When I gun it (my dad's theory to break free stuck parts) it seems to do ok. I can't really tell if all cylinders are firing but it does get up to full RPM.
So, I either broke a piston, valve, or something else right? If the smoke I am seeing is blue/white - that's oil in the combustion chamber right? Nothing good there. Regardless of other issues that may be present, that means show's over right?
Or should I replace the Throttle Position Sensor (which I think is the code P0120) and that could that solve all this?
I am not thinking so...
So, if I have to replace an engine on a 2002 KJ - who, where, how much? Has anyone done this and have recommendations?
Thanks,
Ed.
