1987 Honda Accord - Engine accelerates and bogs on its own

#1

My car will run really rough and bog down and die. It will start only if I floor the gas pedal (it is not fuel injected). Sometimes it will accelerate for no reason. I’ll come to a stop and it is idling at 2700-4000 rpm. I have no idea what could be causing these two things but they seem to come together. I never have this during warm weather, only during cold weather and it is intermittent.



Any ideas on what this could be?



Thanks,

Never mind

“it is not fuel injected”

Sounds like a sticky butterfly valve.
If that were the only problem I would suggest spraying some carb cleaner down the throats.
But the bogging down suggests the carburetor has dirt or other problems.

These carbs were nightmares to service.
A remanufactured or rebuilt carb is your best bet.
I think this car has two fuel filters and they should be changed too.

With some mechanical savvy you could buy a Weber carburetor and an adapter plate.
That’s what I did on my '81 Accord.

Somehow managed to read right past that line. Thanks for pointing that out!
