Hi Guys. I've got a question for the mechanical geniuses.

My 98 Cherokee Sport hesitates when I back it up. It also starts lurching and bucking on the highway after it's been running for a while. Lastly, it backfires internally if you try to start it up but don't turn the key to the on position for about 30 seconds ahead of time.

Any ideas what could be going on? I'm planning a trip cross-country in May and obviously can't take it running like this. I live in a small town and the only "mechanic" within a reasonable drive is a backyard guy.

Thanks a lot.

John
