vibration
Greetings,
Marry Christmas to everybody!
Cherokee 1999 Laredo
There is very slight vibration of the engine. I changed the spark
plugs. It didn't help a lot. The tester in the service did not show
anything. What else could be the problem?
Best regards
Orlin

At what RPM? If the vibration is at idle it could be a dirty throttle
body or idle air passage/stepper. A spray with throttle body cleaner
will fix that.
How do the motor mounts look?

Re: vibration
Dear Doug,
The vibration is constant. However I can feel it more at the low RPM.
Before it was worse. After I changed the spark plugs it is not so
sensible, but it is there.

Re: vibration
May be your harmonic balancer is has spun in it's rubber mount.
Take a screwdriver and follow number one piston up for top dead center
to see if it still matches the timing marks:
