Hello Everyone!
This is my first post
I have a 2000 Cherokee 39k mils, just replaced the head gasket.
the problem that i am having now was their before i replace the Head Gasket.
when i turn the car on the engine vibrates just like if i had a miss fire, but when i changed the head gasket i also replaced the plugs and the ignition coil.
however it still has the vibration. you can really feel it when you put the car in D or R and go slowly

Thanks

 

it might be the tranny mounts o the torque converter check those.

 

Thanks for the replay.
I think i didn't do a good job of describing the problem, so here we go.
the car acts like their is a miss fire and one or more cylinders are not working.
the engine not only vibrates it also doesn't have power. like i said plugs and the coil was replaced, the only thing i can think of is the fuel injectors.
could it be anything else

 

Reseat your coilpack possiably if n'tx2 on the mounts too.Or you may have a bad plug boot.

 

did you check compression? before/after? is the vibration steady and in the floor board? does it stutter when you accelerate? lack of power or runs great just vibrates?

I guess I am asking if its a run-ability problem or a vibration problem only?

i am guessing motor mounts based on it getting worse with the motor loaded to the ground and goes away in park/neutral?

 

i worked on one that did same thing. had a bad motor mount, when motor lifted the back of the coil pack hit the firewall cracking the pack itself. just my .02

 

Dam motor musta spun in a circle to do that?

 

it was all over the place. even broke oil press sensor. that was his complaint. oil guage at zero. he didnt even notice misfire.

 

I have not checked the compression, but its definitely lack of power, and it stutter when i accelerate.
Thanks for all the replays so far

if its sputtering after a heat soak that is normal... on 99 up xj's with the redesigned intake manifold...

 

do a motor mount check have a buddy look under the hood and shift from N to D and see if the engine moves like a wild horse. as it has been said it could have broke the coil.

 

What do you mean??? heat soak...

How about spark plug wires not in the right pattern???

 

im not 110% sure but i think it means the engine temps rise after the engine has een turned off. the engine was running hot and continues to after being shut off

 

I would pull your plugs and inspect them. Also, like an above poster said, try to re-seat your ignition coil, and re-seat the coils over the plugs.
