    Knocking under a load in all gears but 4th?

    That would makes sense, i guess I'll be looking for a AX10 and tcase to replace the BA10

    Knocking under a load in all gears but 4th?

    My 88 Comanchee 4.0l 5 speed was killing rotor. It turned out to be a bad cap and isnow running great, however, now it makes a knocking sound when in gear except 4th. The sound changes speed with the rpms. Does this sound like a dead sync sensor?

    BTW it only happens under a load not in neutral

    Help 4.0l Killing Rotors (Pics)

    It turns out that the cap was bad. The truck is running great now, expect that in every gear but 4th I hear a loud knocking sound that speeds up as rpms increase. I'm thinking that I might have fried the sync sensor, however, it is running better than ever.

    Help 4.0l Killing Rotors (Pics)

    What would cause my 88 Comanche to kill rotors like this? Both of these have less than 150 miles on them.

    Stator? Bucking and Backfiring

    It does have some play in it. How much is a few degrees?

    Stator? Bucking and Backfiring

    It is getting 5 volts to the sensor and i can see the signal pulse on an analog multimeter. How do I test to see if the computer is getting a signal?

    Stator? Bucking and Backfiring

    I have been having issues with bucking and backfiring above 2,000 RPMs at cruising speed in my 88 Comanche 4.0l. After replacing and fixing a number of parts I've narrowed the problem down to the ignition. I test the coil and stator and both seemed fine. I wasn't confident in the stator test...

    Renix issues: stumbling, misfiring....no fun.

    Did you ever figure out the cause problem? I'm having the same issues

    Bucking above 2000 RPMs

    No, I haven't pulled the distributor yet. If it were an indexing problem wouldn't the miss happen throughout the RPM range? Also, under full throttle I don't get any missing or backfiring.

    Bucking above 2000 RPMs

    I've bypassed the EGR and I'm still getting problems. It is starting to get worse and actually backfire through the exhaust. Could a bad O2, air temp sensor, or bad/leaking injector cause this?

    Wouldn't a plugged tube cause low vacuum?

    Strange MAP Sensor Problem

    I have an 88 MJ with a 5 speed. I’m having an issue with bucking above 2,000 RPMs. After testing, replacing and cleaning almost ever sensor and ground I checked the MAP sensor. I got the following specs: A to B 4.01 volts A to C 5.00 volts A to B hot at idle .99 volts (S/B 1.5 to 2.1) I figure...
