I have a 91 780 that sat a bit berfore i bought it.
Check your vacuum lines and replace if you can. usually the ends are cracked.
Also take the time to clean and protect the grounds both on the engine and at various points around the car. Use dielectric grease or copper conductive paste.
Check the grounds to the injectiors and the wiring for cracks also check that the injector resistors are tight in their connectors and that the wires are not cracked coming off the resistors. My wires kept popping out of connector and caused a skipping miss condition.

Maybe wouldnot hurt to clean your throttle body also.
These are all things you can do easily on your own.
