I own a 1988 Honda Accord LX with a carburetor; When I start the car, it races at @2200 rpm but when the engine is finally warm the idle drops like a rock to just above zero; It runs at that level and doesn't recover. Why won't my engine idle between 900-1,000 rpm?

Thank you.

Check for vacuum leaks first and clean carb inside and out with spray carb cleaner. You may need to find someone good at these carbs now a lost art and 26 years old lots could be on the list causing this. Start with what I suggested and note anything that doesn't look right or broken,

Tom,

I've checked for leaks and the carburetor was rebuilt 5 years ago.

The problem is consistent with the normal rich mix when cold getting air in thru a leak anywhere. Carb, vac hoses, intake anything and gasket, diaphragms, brake booster or anything that uses constant intake manifold vacuum. Still has to be ruled out if nothing else.


Carb redo 5 years ago doesn't mean it's still perfect but could be? Gotta start looking someplace and I think vacuum leaking is high on the list to begin with,

Thanks for the help; I'll re-check for any vacuum leaks.
