Running Rich.. where?.. at Idle, Cruising, WOT.. how do you know? Check the Connections on the Temp Sensors at the water outlet.. the ECU uses one, the Gauge uses the other.. if the ECU temp Sensor has corroded contacts, it'll think the engine is cold, and run rich. Fuel Pressure. is the Regulator hooked up to Manifold pressure?.. has the hose come off?.. that will give full pressure at Idle, and less then full at boost ( lean ). You mention Auto ECU.. why?.. is it the ECU chassis that is Auto, or is the PROM Auto?.. or both. Cj
