I've read through and searched several of the past threads on this problem and cant seem to solve it as of yet.
I have a 1996 Cherokee
184k
4.0L
Automatic
What it seems to be doing is misfiring mostly in higher gears when cruising on the freeway, or at lower RPMs in general. You can hear it misfiring at idle once it warms up between 750 and 1000. When I'm on the freeway if I drop it out of OD and into 3rd and drive near 55mph and the rpms are around 2200 its barely noticeable.
I started with the easier stuff and have progressed from there.
Ran a bottle of Injector cleaner with a full tank of new gas
New Spark Plugs
New Plug wires
New Dist Cap
New Rotor
Replaced TPS
Replaced CPS
It has helped a little overall, but not fixed the problem. It still misfires at the above mentioned times and still throws a check engine light.
From this point what would you all suggest it may be?
I do not have an Ohm Meter to test with.
I was thinking that the way it is acting that it could be a plugged injector? What would you recommend to test for this? I didn't want to throw new injectors in it if I dont have to.
