2003 Jeep Liberty 3.7 Code P1296 any one know what this is ?

SOURCE: 2002 Jeep Liberty 2WD 377l v6 won't idle when first started up.

it doesn't have to do with the battery. I just had this same problem. Clean the carbon out of the IAC and test to see if this solves the problem. Should it not, the next step is to replace the Throttle Position Sensor. This is a common problem with this model of jeep. The can of cleaner and the sensor only cost 45 bucks, and about an hour total to do.

SOURCE: code scan: P0301 Cylinder 1 misfire detected

Code P0301 is a generic OBD Code for Misfire. It also indicates you have a misfire in the #1 Cylinder. I would start by checking the plug wire to make sure its clean and on all the way (at the coil as well). Then if that doesnt help I would pull the plug out and check the condition of the spark plug. hopefully this will give you some direction. Thanks for Using FixYa!

The system needs to be checked for cades. Airbag codes are pulled out of the ECU with the use of a scanner tool. A good auto mechanic shop will have this or you can go to the dealer. YOU SHOULD NOT TRY TO REPAIR THIS YOURSELF,YOU COULD ACTIVATE THE AIRBAG!!!!!

P0301 is #1 cylinder misfire detected and is most likely related to a worn spark plug that is need of replacement. All plugs should be replaced if replacing one. Not sure how many miles you have on this vehicle, or if plugs were ever installed, but this is the basic step to take in diagnosis.
