Engine temperature sensor faulty.
Not the one for the gage, but the one for the computer.
it's telling the computer the engine is still cold, and giving it too much gas.
Or, TPS is bad. (again)

Bad injectors. Either leaking or not vaporizing properly.
Black in the exhaust is too rich of a mixture.

black smoke indicates fuel mixture is to rich. that also allows for hesitation. dont know the year, if its older rebuild the carb, or have it adjusted by someone in the know
