95 4.0 stuttering/chugging
Hey guys
My 95 cherokee 4.0 is running strange. It starts right up, no check engine lights, but it kind of stutters/chuggs. It will get up to speed, but still keeps doing it. I just replaced the upstream o2 sensor. Any ideas on what to do next?
Thanks

my 89 has the renix 4.0. so i dont know if it will be the same but my motor kind of chugged and the rpms floated a bit. and i read that if you try to tighten the bolts to the header it helps. Apparently some of the cherokees had problems where the header would slowly loosen itself and make the motor sluggish. It helped on mine, and i actually noticed that my header was kind of loose.
