End Of My Rope

[KC200787]

Ok, I bought a 88 ford bronco with minus a engine...after all the work to get the engine in and running it seems to be feeding entirly to rich mix of fuel to air because black smoke comes out of the tail pipe...Ive replaced the plugs and module (had tested) on the side of the distributer along with haveing checked the map sensor and coil checked, the wires seem to be ok and the timing is dead on.

I seem to be stuck at a point that i dont know what could be causing the problem, the first real thought could be the o2 sensor. Second would happen to be the injectors, but im unsure

My question(s)

1. Is there a way to test the o2 sensor?
2. Is it possible a injector(s) could cause the problem?
Also, the check engine light burns and when idleing it has a little bit of a rough idle/miss


All comments and leads to the cause of the problem will be appreciated

have you check your air intake?

Checked the inline fuel filter as it might be clogged. As with your injector query:
When a fuel injector malfunctions it will allow excessive fuel into the engine. The fuel injector is manufactured with a control valve that allows fuel to flow at prescribed amounts. If this valve sticks open it will flood the cylinder with fuel. This excess fuel causes black smoke from the exhaust system. To test your Ford Bronco for this condition the injector fuel rail must be removed. Confirm that all injectors are still connected to the fail rail. Without cranking the engine over turn the ignition to the "on" position. Without the engine running the fuel injectors must not have any fuel exiting the injector nozzle. If fuel is present at any of the fuel injectors they have failed and need to be replaced.
