Need Assistance - Please Help

Hi all. I have a 97TJ with 2.5L and it has started having some issues that make it undrivable. The problem started out as intermittent sputtering and backfiring that would start and disappear during normal driving, sometimes before reaching operating temperature, sometimes after. At first it only did it under load, meaning in-gear and under acceleration/during cruising. It would go away when I put in the clutch and when it was out of gear. It would also disappear when I turned on the lights. Now it does it during idle and under load, but it still picks its moments to show up. However, there is a new twist. I didn't notice it doing this at first, but now when it happens the volt meter goes dead and the "check guages" light comes on along with the "check engine" light. I'm not a complete noob when it comes to mechanics or working on my Jeep but this one has me completely stumped. My wife says I should take it to a mechanic but I can't justify spending that money for someone to guess at it either. I'm sure I can fix it myself with a little help from my fellow Jeepers in diagnosis. Has anyone had this problem before? Any and all responses will be greatly appreciated. Thanx!

Sorry everyone. This should have been posted in the TJ Tech forum. Can an administrator please move this for me? Thanx!

I would recommend removing your alternator and taking it to the parts store to get it tested. Good luck.

The 97 that I had did the same thing and it was the alternator. I also had sputtering and backfiring when the throttle body needed to be cleaned which was about once a year.
