Same car as my previous posts. There were some broke fuses so we replaced them, and now it's showing our codes. Code 44. Just changed the o2 sensor, so I doubt that's the culprit. Runs really strange, it idles fine cold and warm, but when we drive it we can't put the pedal down at all, especially off the line. Just bogs down. We gotta feather it, and eventually we're able to put the gas down, we just have our troubles off the line and getting it to the point where we can give it more gas. We have a new accelerator pump, just waiting on the gasket to install.

 

Doesn't sound particularly "strange" at all. Quite a normal way for things to go bad, in fact.

Since you say "accelerator pump", I'm going to go way out on a limb, and "assume" this is a carb.

Highly doubtful that an accelerator pump, in and of itself, will accomplish much of anything.

Sounds like it's completely starving for fuel. Might wanna try a new fuel filter; and while you've got that apart, make sure the pump can deliver LOTS of gas when you crank it over with the fuel line discharging into something that will keep loose fuel safe. Like, stick a piece of hose over the end of the line, and point it into a gas can or something. If the pump puts out nice massive garden-hose-looking shots of fuel, then it and the pickup "sock" in the tank, and the lines, are all OK.
