About week ago i was driving my toyota and it started to run rough and black soot started coming from the exhaust.So I checked the carb and decided to rebuilt it I adjusted the float correctly.When I started it up the engine ran fine until it warmed up and started to run rough and black soot started coming from exhaust.
Carb automatic choke sticking closed or your float setting too high causing flooding engine.
Have it checked for free trouble code at Autozone or O'Reilly's . Sounds like a sensor or clogged Cat converter. But it is running rich. The engine temp control sensor or a bad O2 sensor can also cause this.
Well your truck is definitly running rich might be incorect ignition timing
Sounds like its running rich? have you checked all the injectors? maybe one of them went faulty. but I would also check the radiator to make sure theres water in it and you dont have a small leake in the head gasket thus causing more condensation and sutt coming out of the tail pipe.
