2006 Jeep Liberty Owner Comments

problem #2

Oct 012011

Liberty LTD 3.7L

  • Automatic transmission
  • 74,565 miles


Have been having a misfire in Cylinder 6 since last October. I have purged injectors twice, two new sets of plugs, new coil and have had dealer clean carbon from engine. When engine light came back on 3 days after the dealer did the carbon clean they told me I would have to take the heads off and sent out to be machined to clean carbon up. Not sure what to do. I have spent a few thousand dealing with this issue already and am debateting if I should get rid of it. Anyone have any ideas?

problem #1

Jul 222010

Liberty Sport 3.7L V6

  • Automatic transmission
  • 48,000 miles

Everything has been OK since we bought this car new in 2006. Then in the summer of 2010 the MIL light went on. I got out my awesome high-end code reader ( EQUUS 3160 ), and found the P0306 code set ( Misfire on Cyl # 6 ). I replaced the air filter, fuel filter, all the spark plugs with Bosch Platinum + 2's, replaced the # 6 coil pack, and then cleared all the error codes. It worked perfectly, until Feb 27th, 2011.....then the error code P0306 has returned along with P0300 ( Random Misfire / Multi-cylinder misfire ), and the jeep is now running significantly rougher than it has been since the fix. So I'm going to replace the # 6 coil again, and replace all the plugs with their original NGK models. If that doesn't fix it, the only other things left are the ASD ( Auto Shutdown Relay - fires injectors and the coil packs ), or the PCM ( Powertrain control module ) which holds the car's VIN and Odometer readings. They are available aftermarket for around 130.00. I'll update this report when I have more information.
