Have you checked the fuel pressure regulator?Hi Guys.
I have a 03 954 and it running very badly at low rpms, it just wont pull away under 3000 rpm.I took out the plugs and the are black which means it running rich, I tryed to check the choke to see if it sticking but can cant seem to see if it working right. Does anyone know why it would be running rich,
Is the air filter clean?
