1988 Honda Accord DX losing power

I can drive the car for 20 miles fine and then it loses power, but doesn't
miss any. I then can turn the key off for a few minutes and it seems to run
fine again when I drive it. I changed the fuel filter and this didn't help.
I have a junk 1988 Accord and can get any piece off that I need. Anybody
got any ideals what it might be? I blamed it on bad gas at first but that
was several tanks ago and also it doesn't get near as good gas mileage as it
did. The plugs and wires have about 25000 miles on them. Thanks for any
help.

 

Did you replace BOTH fuel filters - one in the engine bay and the other
by the gas tank behind the left rear wheel?

Also, make sure your carb float level is correct - remove the air
cleaner and you can see the level of the fuel on the driver side of the
carb that is adjustable with a screw on top. Start the car, and make
sure the fuel level is centered between the marks by tweaking the screw
1/8 turn and revving to 3000 a few times and/or waiting 15 seconds.
Paint the float adjust screw when done.

My car did this when it was below 1/2 a tank on gas and I
drove on the highway. There was a huge dent in the tank
interfering with the fuel pickup. In the city it was
fine cuz the fuel was sloshing around, on the highway
not so much... Needed a new tank.

This is not a carb problem, but a 'pre-heated air' delivery problem.
Check and repair the vacuum line to the air diversion damper
in the air intake. The carb needs 100+ deg F air in the Winter.
Pre-heated air from the exhaust manifold prevents frost and ice
build up and might boost your mpg a touch. This happened to me
years ago and a five minute fix was all that was needed. Good luck.

 

Same exact symptoms. Just fixed this after a year of trying. It was the
fuel pump.
