A new service calibration for the powertrain control module was released to address a sag condition, as well as others. I recommend receiving this calibration from the dealer. There are any number of internal transmission problems that could be related to this concern, as well as engine mechanical problems or ignition related problems (spark plugs) that could cause this condition.
There are several things that can cause your 1989 Oldsmobile to hesitate. Dirty fuel injectors are the most common cause.
not near enough cause i don,t own one
cracked or broken wiring, blown fuse
low trans fluid level.
you have to be more specific for a proper answer... at what speed does it shake?.... 40mph> ? what do you mean mist?
If there are no visible leaks....a blown head gasket.
if it smells like antifreeze inside the cockpit then your problem is the heatercore, since you can't see it.
It will, if it causes the fuel mixture to be out of range.
Expect 26 city, 34 highway in realworld. EPA estimates and different driving styles may cause variation.
if you have overdrive in that car it means that your about to go into overdrive
dead battery, blown fusable link, severely cracked or corroded cables. especially check battery ground to chassis and engine.
Check for a busted engine or tranny mount.

Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
Had the same problem with my 92 cutlass ciera. It turned out to be ac compressor. Probably the clutch.
A faulty fuel pump would cause your Navigator to hesitate when you accelerate. Bad gasoline could also be at fault.
A bad radiator could be the cause, or the car might have a blown head gasket which would cause it to overheat.
There are several things that can cause your Ford E2 50 Van to hesitate while driving. The most common cause is a malfunctioning ignition switch.
The high idle may be caused by old spark plugs and wires. As far as the temperature problem there are several things that may cause this, but the thermostat is the easiest and cheapest thing to check.
Test for fuel pump pressure at the back for the throttle body at the schrader valve. Your fuel pump may be going out. This is the #1 problem with these cars.
