I have a 89 xj 4.0 that misfires/stutters with medium to light throttle, most noticable on the highway, just replaced the ECU for no #6 injector, igniton is new from the coil down to the plugs. Any one seen this or have any ideas?

Thanks

i had the exact problem. does your idle act a little weird also? maybe a little high?
