2003 Jeep Liberty , Runs and Drives but needs work, is misfiring.I did replace all the spark plugs to check. Sometimes doesn't misfire and then suddenly does again. Not sure if it's electric or something else. Got a bunch of stuff fixed on it last year, new drive shaft for 4x4, new power steering brackets, this year got a new water pump after a break down and hasn't drove the same since. I decided not too sink any more money into it, and got an older decent truck. I needed something reliable for work and school and couldn't have this sitting in the shop forever. Hoping someone with more skill or expertise can fix it up and hopefully get much more use out of it. I did drive it everyday still until I got the truck almost 2 weeks ago.Part of me hates to lose it but I can't afford to get it running properly amd could sure use the money for college.
