Adjusting ignition timing on 4.0
Is there any way of adjusting timing? I have distributor, but found no timer marking on flywheels

None of the flywheels have timer marks. 
(OK, that you can see). There IS a mark in the "crank pulley" up front. (I call that a damper pulley...). And yea, the computer does the timing. "flywheels" are for manual tranny (with clutch), but most of us have a "torque plate", to connect our torque converter to the end of the crank. Ether way it's your CPS on the bell-housing that tells the brain when to spark the spark.
If you have a problem, and post your code, there are guys here who are pretty good at that. (and the year could be more clear)
