Running Rough
1990 cherokee laredo, 4.0
between 800-1800 it runs rough and backfires but above 1800 it runs perfect.
i dont know what it could be, I think it could be the throttle position sensor or something. HELP me out guys. Thanks

Check the intake manifold for loose or missing bolts. If that isn't the problem look for leaking vacuum lines.
