1995 Toyota Corolla Repair Question
Why do i have black smoke from the exhaust
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?
That one thing I haven't replace yet
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.
