Hi Everyone:
Here is the problem. We are running a MERCRUISER ECM MEFI-3. There is a Mid-Range misfire at about 1500 RPM.
The boat idles good. Runs good at wide open throtttle. The Wires, Plugs, Distributor Cap, Rotor, and Fuel Filter have all been changed but the problem still exists.
Does anyone have any idea what could be causing this or any suggestions on how to correct it?
Also, does anyone know where we might be able to get a reasonably priced MERCRUISER ECM MEFI-3 Scan Tool with the diagnostic codes?
Again any suggestions that would help to correct this would be greatly appreciated.
Thank you for your time, consideration, and cooperation. I hope to hear from you soon,
David
