Help, Black Somke Ranger 89 2.3

[Saint Gabriel 89]

Hello, my name is Gabriel and im from Mexico, my english is not the best but i hope you can understandme.

Im a proud Ranger owner but im a bit sad now because i cant find the problem, since i bought her i had been dealing whit black smoke, carbon and gasoline smell in the exhaust, i changed IAC valve, new spark plugs, cleaned the injectors but the problem is still there.

Can some one help me please?

Thanks a lot.

my bet is fuel pressure regulator, take the vacuum line off the regulator and see if there's fuel present when you turn the key on, my next guess would be a damaged or stuck open fuel injector.

fuel pressure regulator or bad vacuum line to the MAP sensor.. or a bad MAP sensor/wiring
