Car idles slightly higher in park or stop and jerks back

No , sounds more like a TPS - throttle position sensor problem .

this is normal as there is clearance built into the parking pawl in the transmission to make it easier to go from park to a gear. I`m guessing this happens when you put the car in park on a slight incline. if you walk up to any car and push against it when its in park it will roll slightly until the clearance is taken up in the parking pawl, this is the clearance that you have.

jerks when?

moving the shift lever. with hand?

moving car. in gear,name the gear, drive, L or reverse?

jerks from, 1 to 2nd gear, 2nd to 3? or ? (or when IT down shifts)

pretend we are blind (we are) and cant drive car,(hopeless) and

tell us exactly what works and dont work driving.

hot /cold engine, fast /slow/ accelerating/ decelerating, up hills and what gears.



if engine is hot, is your idle at 800 RPM parked, in park.

y/s

if not the idle controls are out of control and when you shift to drive

IT will jerk. this is an engine problem.

there are lots of other symptoms.

the idle RPM is too high
or its just too cold,
how cold is it outdoors?
idle speeds cold can be about 1500 RPM/ cold.
and will ****.
it jerks because you are taking 0 torque from engine
and the sending that to a stalled rear axle.
this cause a ****, that is why the park lock out requires Brakes on
so yo dont run over things.

Front brake rotors need to be turned and new pads. Adjust rear brakes. the front brakes are doing all of the stopping. (overheating the rotors, premature pad wear).

Not fuel filter. Is your engine light on? Could be accelerator pedal position sensor. Does it do it only when you are accelerating?

Have engine wiring harness checked as 1993-1995 MB's were forced by US to use biodegradanle insulation on its wires. If thats not it replace coils and do a tunes up.

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

Have you changed the trasmission fluid and filter in your jeep lately, if not do so and that just might stop the jerking in your jeep, and if that does not do the trick you will need to have your trasmission checked out by a trasmission shop.

change plugs
