Running rich

I have 1986 2.5L s10 p/u. It is running rich and seems to be flooding and also is putting off very strong exhaust fumes. We changed the map sensor but it didn't help. Can someone suggest something? Thank you.

RE: Running rich

See if the injectors are stuck open instead of opening and closing.
I have seen a bad ECM holding 1 or 2 injectors open all the time

RE: Running rich

i'd say try a new ho2 sensor.. i've seen a few ho2 sensors making the comp think it's running lean so it's dumping fuel into the engine
