Why does a person have his blood pressure checked on a regular basis?
A basic tune-up would involve replacing the spark plugs and possibly the plug wires. The fuel filter may be replaced and all fluid levels checked. Before electronic ignition systems it also meant to replace the points, rotor, condenser, and inspecting the distributor cap.A basic tune-up would involve replacing the spark plugs and possibly the plug wires.

Have the fuel pressure checked should be about 40 I think but a GM dealership could tell you for sure also there should be a fuel pressure regulator
The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.The pressure is checked with a gauge, the electronics are checked with an appropriate scan tool and a volt/ohm meter.

Check to see if there is a internal advance mechanism in your distributor. On older GM models bushings would wear causing it to stick and causing a surge or bucking as the advance within the distributor would release. Your computer regulates the advance, however, have the distributor checked.
Remember that the number one problem with these vehicles is the fuel pump. Have you checked for fuel pressure?
Have you checked all of the High Tension leads from the distributor to the plugs, or just one or two? Same with HT lead from Coil to Distributor, Check Distributor cap for cracks
