There's really no accurate way to check the timing on the Magnum engines
with conventional tools. Even a scanner will fluctuate on ignition timing.
The '89 was still in the era where you could check timing...but not anymore.

You can't check the timing like that on new computer controlled vehicle, the
jumping is as likely to be the computer doing it's thing. I am not sure of
the procedure for your engine but my 89 Dakota and other DC products I have
you had to pull the plug on the to the temp sensor while the engine is
runing to put the system into limp home mode. That is the only way you can
determine the base timing setting.
Do not use those results as a basis for changing the timing chain.
