I had an 85 Monte with the 4.3 V6 in it.
**You may have a Vacuum line that is leaking or off somewhere.
*Could also be the Catalytic Converter is plugged.
*Or the fuel filter may need to be replaced.
I am assuming that the plugs are good and the wires are good the Distributor has no issues, and the Air filter is good too.
