Perhaps someone else has had this experience. I'm about ready to throw my hands up.
90 xj, 4.0, aw4, 231. The engine sputters pretty bad right about 2000 rpms. It goes away when giving it gas or letting off the gas. does't matter what gear it's in, just feels worse on the freeway. probably because it's in overdrive. goes away over 2100 rpms. no problems under 2000 rpms. i've check every thing I could think of. Finaly I took it to a shop for a ignition and conponant test. they had it for several days and could not find it. they gave it a good going over. didn't even charge me. they said everything checks out that they could test. I was advised that it could be a conponant that is going out that the testing could read or read as a good conponant. I was told the next step was to just start replacing parts to find it. starting with the ignition module. they figure its an electrical or ignition problem. A new ignition module cost about $140 and it might or might not fix it so this could get pretty expensive. I'm hoping someone else had this problem and can point me to the right direction. by the way the motor only has about 500 miles on a complete rebuild so it has a new cap, rotor, sending unit, filters, rv cam, etc. checked to make sure all the vaccum lines are were they are supposed to be. switched out the coil no fix
