I have a 1990 Chevy Suburban 350 small, 1500. I think it may be dumping fuel.When I press the accelerator The vehicle bogs down and wont go. I've found that i have more luck getting it to go when i gently push the accelerator VS. when I Give it more gas. Its fuel injected at the carburetor. I have already replaced the coil, distributor cap,rotor,fuel pump and fuel filter. how can i fix this?

i would look at the timing to be correct.
i would make sure the trans is in good condition.
lastly, the cat converter could be clogged not allowing the motor to breathe.
