87 honda accord runs out of steam

My 1987 accord 2 bbl carb 2.0 l engine atomatic with 87000 mile on it
seems to quit acceleration if you give it too much gas for too long.
It just kind of quits, slows down, quits, slows down. If I let off
the accerator it seems to pick up were it left off. If I press the
fully gas pedal I can accelerate normaly for about eight second then
it does what I described.
I have changed both fuel filters and checked the fuel pump fuse.
Any ideas appreciated.
Thanks

Is the vacuum advance working? Does it always quit at a certain rpm?

 

Kinda sounds like a flaky fuel pump. What I would do is pull
the air cleaner covers, etc, and check the little glass window on
the side. Have someone watch that window while you do the gas.
Normally, the level should be at the halfway point, on the dividing
line. See if the level drops way down at the point it's gagging.
If it's the pump, it would drop down low about the time it gags,
but then fill back up to the normal point when idling. The demand
for fuel at idle is low enough for it to keep up with.
If the level stays at halfway no matter what, it's probably something
else.. Filters, etc, cept you say you changed both of those already.

i agree fuel pump..good luck..


SCRAPPER....

 

Your other replies overlooked the obvious- clogged catalytic convertor

yah that even slipped by me..on converter or converters....

 

nah - effect of that is pretty much immediate, not gradual over 8 seconds.

 

No. Partially clogged converter will let you drive but wont flow enough
to get to highway speeds. When you try, the thing gets so hot I saw one
that started a rear seat on fire!


I had one fail on the interstate. Luckily the spring connections
"popped" and let enough exhaust by so I could get the last 5 miles home.

sure, but it's constantly restrictive - it doesn't kick in after 8
seconds. the problem sounds much more like fuel starvation.
