Why do i have black smoke from the exhaust

I have a 1995 Toyota Corolla 1.6 motor and I have black smoke coming out of the exhaust. This is what I've done to provent this from happening. I replace Map Sensor, Air Charge Sensor, O2 Sensor, Catalytic Converter, Coolant Temperature Sensor, Temperature Switch, T.P.S. Sensor, Fuel Injectors, Fuel Filter, and a full tune-up. After all those replacements is there anything else that I may have miss?

You hit it all. Are you sure it isn't burning oil?

If so will that cause fuel enrichment?

No, it wouldn't. Have you made sure the fuel pressure regulator is working properly?

Do a fuel rail pressure test and check for a leaking injector,

The last thing to check would be the ECM.

Will the wrong ecm cause fuel enrichment? Because I have a 1.8 ecm that is running a 1.6 motor

Well the reason of black smoke is incomplete combustion.since u have removed all your engine parts i suggest you to check out the pistons as well.

If you have a different ECM, that can cause the problem. It could be causing the different air /fuel ratio. Thus, a rich fuel mixture.
