Engine seems to "miss" at highway speeds.

'94 Cherokee Country, 2WD, auto trans., 4.0L I6.

Has been running great around town when it would start (see other thread) but will "miss" when I get up to @ 68 MPH. It feels much like when you have a spark plug wire laying down.

There is a 5 MPH band there where it runs rough...not enough to decelerate...just enough to cause lurches and jerks in the ride.

When I accelerate past that band, things smooth up again until I hit @ 80 where it will do it again.

I'm confident this isn't tire related, it's definitely in the powertrain somewhere though I can't say it isn't the transmission.

Also, it doesn't do it at higher RPMs in the lower gears even when I accelerate hard enough to get the RPM's that high. It just does this at those highway cruisin' speeds.

No idiot lights come on when it does this either.

Anyone experience something like this?
 

My 1993 jeep cherokee country 2wd auto. i6 4.0 does the EXACT same thing. Only happens to me at interstate speeds too. I have tried to solve this problem to no avail. It has been going on for over 1 year. If i find a solution i will let you know. If you happen to find one please let me know.
