Focus Failure 2001

I have a Focus LX 2001 fault, the problems is that it loses power after a while of being running and turns off, well previously it did it more but I change the coil and improve it a bit and now it only loses power and sometimes it marks the check, the scanneous and it appears too rich for the regular one only passes when it is day, it is as if it is heated. I hope you can help me, greetings

I need specific fault code and if your scanner is displayed by Frezze Frame data to help you greetings

You could expand the data, if when you fail to make black smoke, it does some exploration, they already checked the preservation of gasoline pump, they already checked
false contacts in the coil wiring, if you show any
individual spark plug failure (this is detected in the mofle as a papalteo)
in short it is difficult to diagnose with such few data

The last fault that I present was that when accelerating loses power. He turned to Chechk's symbol on the scanner appears P0303 Bad Combuistion Cylinder 3 P0172 System too rich (Bank 1) and that is what always appears already changed spark plugs, cables, pump, and nothing. I hope this information is more help greetings.

Hello, refer to the distribution strap, did you change it recently? They didn't leave her out of your way? a little back? How is the coolant temperature sensor? If you work badly when heating the engine does not send the real them
