I have a 96 Ford Contour 4cyl DOHC. The original miles on the car is 169,000 but the enigne was replaced with another that had 40,000 on it. Recently it lost engine power. A hand computer stated the code was for a Mass Airflow sensor. I replaced it & the code went away but there is still no power. I changed the fuel filter & the fuel regulator. I changed the spark plugs. I have had the engine timing and the catalytic converter checked. We have checked everything fuel related and still no power. When it idles it's fine. It's only when you put it in gear that the power loss occurs. I was also told that it had nothing to do with the transmission. Any help?

I am assuming that the replacement engine ran fine for a while?

Did you disconnect the negative battery cable for at least 30 seconds and drive it for a while?

Any other codes.?

What do the plugs look like? Is the spark fat and blue? Does the engine heat up properly? What fuel pressure?

Check the O2 sensor.

Good luck and let us know. :)
