Cutout past 1/4 throttle

Hey guys, I'm new to the forum and new to owning a 1989 prelude with a B20a. I took it for a drive around the metro here in kc and discovered after driving it for 45 minutes or so that after 1/4 it started to cut out. The more gas you give it, the worse it would get. At full throttle in any gear except 1st and 2nd it would be so bad that it would be as you if would be pressing the pedal to the floor and back off repeatedly. I haven't really dug into it yet. I have some ideas as to what it could possibly be. If anyone has any suggestions, ideas or has had this issue before, please comment. Anything helps, Thanks!

"metro here in kc"

By this do you mean here in King County? If so PM me and we will set a time when I could look at it in person.

I want to say it's the stock fuel injected b20a. The guy I bought it from said that it was swapped but I don't believe him one bit. Just like being new to this forum, I'm new to Hondas

Re: Cutout past 1/4 throttle

Is it auto tranny?

Sometimes it forgets to downshift.

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

If it really is a b20a then the previous owner is being truthful with you. Your car would have come with a b20a5 not a b20a. No 3rd gens produced for the US came with a b20a.

Re: Cutout past 1/4 throttle

its a 5 speed manual. ive been doin dome reading and yes it has been swapped to a b20a. i know the gas tank has some rust. after pouring the fuel filter out, the fuel keeps getting more rust brown the more it empties. after putting a new filter on it still does the same thing. i want to pretty much replace the whole fuel system with new parts tank, lines, pump, ect. but i wasnt sure if thats where i should start.

Re: Cutout past 1/4 throttle

There is a filter in the tank too. If it's as corroded as you say then that's probably plugged as well. It's also called a "sock", as it fits over the end of the fuel pump. You can still get a new fuel tank from Honda, and I would recommend that you do that if you can't get salvage yours. But first remove your tank and see if you can clean it out. It's likely that the baffles are compromised, and you may need to replace the tank even if you can clean it. Here is a link to hondapartsnow.com in case you decide to replace with new, item #3...
