My fuel injected 302 is running rich. I don't know much about fuel injection but I know in carbs you can adjust the fuel flow and idel speed. Is there any thing I can do for it?
Pull codes and see if the computer detects any faults. O2 sensors can fail, causing a rich condition, as well as the fuel pressure regulator. The best place to start is with the codes. Fuel injection parts are expensive, so it is best to narrow it down to the exact problem before buying random parts hoping one will fix the problem.
Check the vaccum lines going to the map sensor, mine was melted on the back of the head, had a heck of a time finding out why it ran so rich. Check the simple CHEAP things first
