Grand cherokee jerking movement

we cant drive car, so jerking is not clear to a non driver.
see>?
first off , ill guess there is no odd noises.
and that means jerking can be 2 things (sure more but)
engine jerks, does it only?
or transmission slips then stops slipping resulting in a jerk.

get it serviced, with persons that can drive and experience this live.

Check Mass Air Flow sensor.

Well if it is miss-firing, it could be an ignition or fuel problem, or something mechanical.
Is the check engine light on ?

Have you checked the transmission fluid?

no good

I'm confussed; you post your problem in the Jeep 1995 Grand Cherokee area, but say us that you have an Jeep Cherokee SE... :-S

For solve this subject, maybe you need review the fuse box in the correct Jeep model:
- Jeep Cherokee (Page 3-5 Fuse Block / Page 15-17 Power Distribution Center)
- Jeep Grand Cherokee (Page 7 Fuse Block / Page 9 Power Distribution Center)

I hope help you with this (remember rated this help) Good lick.

sounds like it might be in 4wheel drive may stuck there

That's a tough problem to solve online...could be from fuel contamination (usually water), ignition shutting off for a second or throttle position sensor with internal wear. (internal switch problem) Or a problem with converter lock-up in transmission or trans control. Or, a million things in-between. Check codes first and see if anything helpful is in there, do some "wiggle tests" on wiring to see if engine falters when running, Have fuel checked for water, and have trans checked for good electrical connections. Largest problem is that even the best equipment will not be able to find a fault if it's working while being tested. Yours is the kind of problem that shops dread...it takes a lot of testing and a bit of luck to find and fix, and if they can't it makes them look bad.
Could also be that I read this wrong and perhaps jerking is in steering etc?

Look for noise in the TPS circuit that can cause TCC to lock and unlock.

check your tps
