#2 of 117 2003 Jeep Liberty Problem Codes by jcarv76

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.

Check for any maintenance-gram pertaining to 2003 engine mis-fires. The Hayes or Chilton manuals for the Jeep Liberty should include a listing of computer fault codes.
  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 have a 2002 jeep liberty that is also comsuming coolant. I had my jeep pressure tested and checked out for leaks and nothing showed up. I had a new head gasket and manifold and I'm still consuming coolant. Has your coolant problem been resolved yet?

Send in 4 ounces engine oil for an analysis. They will tell you if it has high sodium or other contaminants, which will point to head gasket leak or engine block crack.

John,
  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.

Wow, 2 bad cylinder. Good thing its just under 70,000 miles.
  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.

John,
  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.

I also had a bad cylinder. The "spring broke". Cost $1.14 for the spring - $350 for the labor. that was two weeks ago. Now I have a "catch/hiccup" when I deaccelerate. It stopped on me with no notice again this week - in a dangerous intersection. Garage/dealer has had it two days "can't find anything wrong". I'm picking it up tonight and will probably sell asap. NOT what I wanted to do!!

Could you let me know the trick to reading the codes.
 
I Have an 03 with the check engine light coming on. I had the code read and all it said was misfire on #5. The light is on steady.
