Okay, this is getting silly. On the way back from MIT tonight, I had a little episode that crops up every once in a while with my YJ. It's done this maybe six times in the 1½ years I've owned it, but I was wondering if anyone else has had this happen, and what they problem/solution was.
I'll be cruising down the highway at a comfortable 70 MPH, straight and level. Suddenly, the engine will stop firing for 1-2 seconds, then pick back up like nothing ever happened. It has ONLY ever done this on the highway, and extremely rarely at that; has never ever happened on the trail or in town. Environmental conditions seem not to matter.
But being faced with an involuntary axle swap, I am now wondering if something else is wanting to crap out on me. Year model and mods in the sig.
I'm sure someone's going to want to suggest replacing normal wear components of the ignition. I've done that (plugs, wires, cap & rotor all <1 year old), and had the injectors cleaned.
Well, I can safely say it's not the catalytic. I have a Random Tech cat w/ less than 10k miles on it. My YJ did this both before and after I installed the cat. So at least that one less thing you need to replace to troubleshoot, Razskidoo.
sounds like on of those 'shorts' that are hard to fine. set the parking brake, start it up, and start wiggling wires. You'll know when you find it.

well...the same thing happened to me out of the blue while i was 100 mies from base. lol ...now anyway...but it turned out to be the igniton control computer was bad intermittently..the problem would come and go ,until one day the engine started backfiring like anything and wouldn't start again...replaced that module ..it can be tested at the dealership....and haven't had any problem since ..also it increased mileage by about 3 mpg..and it gave no indication beforehand that anything was wrong
