Jeep Liberty Problem Codes and TSBs
My Jeep check engine light started to blink, and the engine is running really rough. From the posts listed, I found the problem codes: P0300, P0301, P0302, P0455, and P1196. The first three codes I saw listed in this forum as plug misfire codes. This would explain the rough running. However, any idea what the other 2 codes mean? I'm also having an issue with coolant level. The engine seems to be consuming coolant. I don't see any pools or leaks from any hoses or clamp areas. :confuse:

A good technician should only see fault codes as a troubleshooting guide, not the root cause. Misfires could be anything from faulty wiring through the firewall, fouled plugs, defective computer chip, bad distributor cap or rotor, faulty spark plug wiring, weak fuel pump or fouled fuel filter, etc.
If there is an internal antifreeze leak into the cylinders, I would be looking for white smoke. Blue smoke for oil, White smoke for antifreeze. This would indicate a bad head gasket or the head is warped. Warped heads will distort the alignment of valve guides and any associated mechanics.
I would tell the technician to get the car off the diagnostic machine and into a maintenance stall and do some real troubleshooting.

I got those problem codes using the key trick on the ignition. It ends up I have two bad cylinders. Fortunately, I only have 69000 on the car so the 70000 warranty is covering this.

Half of me is curious why those 2 cylinders (bad rings, faulty piston rods, improper clearance between bearings on the crankshaft, etc). The other part of me would only settle for a new engine, NOT a rebuilt engine or either a partial repair of the two faulty cylinders.
Since it under warranty, the dealership service department (in an ideal world) will fix it like new. But we don't live in an ideal world, but I hope the dealership does what is RIGHT, and not they can get away with.

I didn't get the total details on what went wrong, and what they're planning on fixing. Good point on the new engine idea. I brought the car to the dealer, and frankly I've had it with them. I'm going to call them in a few minutes to discuss options. :mad:

This is the worst problem I've had with a vehicle ever.
There is a lawsuit in the future on this problem for sure.

There are others too. Google search OBD 2 CODES
FYI, the exact two codes are:
P1491 Radiator fan control circuit problem (may be solid state relays as well as other circuits).
P0153 HO2S Slow Response Bank 2 Sensor 1
Thanks for any help!

We're thinking of fixing, selling and starting over with something else. It's a little frustrating to have major problems after only 74,000 miles.

thanx for the help
but I did notice onset of symptoms, if tank was low 1/4 tank gas, would rev. Also noticed when acting "funny" interior windows would frost-condensation. So, I tried running heat, thinking low tank, window condensation vehicle, no engine light, seemed to run fine...
Tonight, 1/4 tank gas typical acting funny time- I ran heat continously-no problems.
Does anybody have any idea what is going on-when engine revs, It's like gas pedal sticks-dangerous situation. Please advise :confuse:
This helps a lot, will driving till I get the issues resolve cause any damage to the engine/car or can i drive with the issues this way? I am away from home for work and can probably get the vacuum issue dealt with. Is the part for the p1250 issue dealer or auto parts store.
Thanks
