The next step is to read or have your trouble codes read. My first guess is vacuum in the fuel manifold is not adequate or the pressure regulator is not working right. Are we sure the spark timing is OK and the air system is O.K.?

Check the ground wires at the battery one of the small wires is the computer ground. If you know were the EEC proccesor is check pins 20-40-and 60 these are all of the grounds. Did you replace the EEC relay also?
