So I got somewhat suspicious again after I was told my engine was shot, and I took it to another place who actually pulled the head and said it isn't shot. But, there is some mysterious reason that it keeps cutting out and hesitating. They replaced the computer, which didn't work. They're going to have to keep trying different things until they figure out what is causing it to lose signal and misfire. Ugh!!!!! I want my Jeep back NOW! One positive: I didn't realize how much I'd miss it until it has been gone for two weeks.
