Put a new cpu in it new cap and rotor , new
fuel pump, ignition module, tried practically
everything I could think of and still haven't
fixed the problem
Have you replaced the hall effect device in the distributor? You should also check and clean the grounds for the EEC relays, sensor grounds and EEC module grounds.
Just got a brand new distributor
New or rebuilt?
Ok then dig out your wire brush and ohmmeter and start checking and cleaning your grounds.
