The hhep Idles like a champ. But when you are driving down the road it will all at once just cut off, not the running out of gas cut off either so it aint the fuel pump. Any body have a clue? and even with it being a 5-speed it will not just pop the clutch to get started when this happens but turn the switch off and back on and most of the time it will fire right up. Me and daddy both think it is the coil what yall think?

You might check your cps, they tend to do this as they start to go out.

I had a similar problem. you bring it off idle and it dies corret? if so, it is your TPS or Throttle Positioning sensor.
This goes out with just age, or from MUD. It was a $90 part for my 97 from the dealer

I got mine for $20 at auto. I would just replace it and see because even if it's not the problem, chances are it will go out anyways shortly.

I just changed a crank scenser in an 89 yesterday after on and off working on the jeep over the last few days with the owner... fixed the problem.. his would just heat up after about 1/2 hour and die.. would not start again and it would idel like crap then run great for a bit..

I had this same problem this week. Mine ended up being a couple of bad plug wires...and my 1st and 3rd plugs were halfway out. Any ideas on how that happens???

So how did you figure out your problem?

finneys98xj · 05-03-2009, 03:37 PM

I fix it yet still waiting on cash for a coil to see if that fixs the prob.

Kyle · 05-03-2009, 11:24 PM

You going to lift? Figure you may aswell since you are getting new coils anyway.

Now thats what I get for doing too many things at one time. I was thinking this was the squeaky coil thread. Please disregard my previous statement

I'm going to lift as soon as all of the kinks are work out(tune-up, new front end bucshing, and get the speedo working).

I pulled the coil off to prepare for the new one which should be here monday. And the old one is crack in five different places. So I belivie I found my problem.
