Hey, I have a '91 cherokee with a 4.0L. For the last couple of weeks it's been Misfiring pretty erraticly, sometimes it will run just fine, and other times it misses so much I can't beleive I'm driving it. It ususally Idles fine (but not always) and it seems to happen most frequently just as I'm starting to accelerate, it'll also hesitate at freeway speeds ....haven't seen a check engine light since this started happening. Sometimes when it's missing really bad, it seems like it's not shifting when it should be (but I could be wrong)
I've replaced the distributor cap/rotor and the plug wires (the plugs look fine). I replaced the lifters about 2 months ago. Six months ago (when i bought the truck) I replaced the fuel filter, air filter, oxygen sensor and throttle position sensor.
Thanks for any help,
Jordon
