Trying to figure out what’s going on. My 2000 cherokee has a horrible misfire feeling like the vibrations and not running right but only when the rpms are between 1500-2000 after that it runs perfect. I have no misfire codes but when I’m driving and it drops into overdrive I get a horrible pulsating vibration but only when accelerating cause as soon as I let off the gas the vibration goes away. Does it every time I go to drive it. I’ve been told the crank bearings ? Or torque converter? I’ve changed the spark plugs-coil-injectors-fuel pump and a bunch of sensors and nothing has helped

I recommend you figure out first if it’s while moving only. Many different ways to figure it out. Depends which one you have the capability to do and are comfortable with. Might not be misfiring.

Still acts like same while in park or neutral. The vibration is not as bad as while moving but still has the misfire feeling as between 1500-2000 rpm and once I’m pass that it smooths out
