confused Acceleration issues.

Well I will get right to it, so here is the issue.

When I am at a stop and push hard on the accelerator the motor seems to just bog down like its going to stall but doesn't, then it picks back up and then starts to move. Also if I have to let off the accelerator real quickly the motor will stall out(this does not happen often but it does happen enough to be concerned)
My question is why would it be doing that? and what can I do to stop it from happening? I will be getting my car out of storage in a few weeks and I will be trying to figure this out, your suggestions would really help me out.

Re: Acceleration issues.

This happened to another car of mine and a good cleaning to the ignition coils and a tune up seemed to do the job, also replaced the fuel filter and it was somewhat clogged when I took it off. But after all that, it got better. When's the last time you tuned her up?

Re: Acceleration issues.

It has a carburetor correct? Bogging down during acceleration sounds like a bad accelerator pump. The stalling out during sudden deceleration, probably fuel related also. Might be time for a carb rebuild.

Re: Acceleration issues.

Thanks for the responses. I will answer the best I can in a way that should be easy to read lol.

-Cleaning of the ignition coils? what would you do to do that?
Well tuning has been an ongoing thing since I bought the car. I have replaced the fuel filter(about 2 summers ago) but it may need to be done again, its not that expensive so I think doing that will be on my list for once its out of storage.

-Yes its a 2bbl carburetor on my 351 Windsor. I have replaced the power valve. and cleaned the carb and replaced the jets in it. Is the accelerator pump something different?

Re: Acceleration issues.

Not for sure which carb you have but the power valve and accelerator pump are different.

Jwko I was given a schematic for a Ford 2 bbl carb. I see the difference now.

In a few when I get my car out of storage I now have a nice little list of things to try to fix my issue. The great thing about these forums is that you can get tons of knowledge from knowledgeable people and from people who have had the same or similar issues and already have an idea what to do to fix them!
