Low-speed instability in a 2002 Platina. Published by manual-mecanica
Good day everyone, I have a problem with a 2002 Platina. The car starts, but it idles roughly, and when I accelerate, it emits black smoke and smells strongly of gasoline.

I've already checked the ignition coils, and they're fine. The spark plugs were replaced a month ago, the throttle body has been cleaned, and the oxygen sensors have been replaced. A blown injector was replaced, as well as the intake manifold gaskets, and I think that's all.: P

Oh, and the muffler was also replaced, and the catalytic converter was removed.

But my problem persists. I hope someone can help me. Thank you.

Hi, I'm Carlos. Did you measure the fuel pressure?.

What you have is excess fuel in the mixture. Check the temperature sensor, to begin with
