My name is Josh. I recently purchased a 1995 Jeep Wrangler. I love the thing to death, but no one I know can figure out a problem I'm having with it. It will start up fine, and run great for a while, but after you start driving down the highway for a little bit it will start sputtering horribly, decelerating even though my foot is still on the gas, and backfiring really bad. After about a minute of this, it will straighten out and run fine for a while, but it happens often. I have taken it to two mechanics and it still isn't fixed. One of them tried to access the computer, and it wouldn't talk to their diagnostics tool, I have a feeling this may some how be connected to the problem, but I don't know. Any help is appreciated, thanks in advance.
