Tune up procedure. - 1996 Buick Skylark

The only tune-up procedures for diesel engines are to change the fuel filter, drain the water separator and check engine speed. If the injection pump or timing belt have been removed, pump timing must also be adjusted (see Fuel System ). See General Information And Maintenance for filter and water separator service.

That will indicate what sensors are not allowing the ECM to run the tune op procedure every minute
It will indicate if plugs or HT leads are faulty, coils are faulty , or the correct air/fuel mix is not being achieved

For most modern cars (less than about 25 years old), a tune up consists of changing all the filters (air, fuel, oil with oil change), spark plugs and spark plug wires (if equipped). Your owners manual may suggest additional procedures.

Sounds like its time for a tune up. Start there and your mechanic will be able to note any other abnormal conditions. change fuel/air filter and any other maintenance items you haven't done so far.

the only procedures that would classify as a tune up on an '05 vehicle would include changing the air filter,fuel filter, spark plugs and PCV valve.ignition is 'solid state' and timing is computer controlled.
