do a search, there was a rather large thread on this issue. Some of the problems were remedied with a little injector cleaner added to the gas. Some fellows were having soot buildup in the throttle body. One fellow said he had a tank of bad gas. So see if u can fix your rough idle with some of those thoughts. Mine idles smooth as silk.

 

I don't know why you guys are always bashing the longevity of the body and frame. Jeeps were make to go off road but you have to CLEAN THEM WELL! Every vehicle is susceptible to rust and deterioration when taken off road. This is my second 4X4 and when I sold my Chevy it looked brand new. Unless you live up north with salt roads, it's going to corrode. LOL. Just keep it clean from top to bottom and I bet it will last just as long as the engine.

Now the electronics I bet will not. I have had more electric problems than anything else.

 

Same as previous posts. Mine is so smooth I can't tell if it's running. As for the longevity, it doesn't matter to me if it lasts 50,000 or 500,000 miles. I like the lifetime drive-train warranty.
