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.
