92-94 honda accord idle problem

Do you have an early 90s honda accord that has an unusually high idle? Then as the engine warms up the idle might fluctuate up and down?
This is caused by the coolant passage to the idle control system that is clogged up. Try flushing it out first with water pressure such as a garden hose, and if that don't work you may have to remove the hoses and pipes and the idle control system to clean out all the coolant passage.

Honda Accord 1991 idles high then low


)The fact that thge engine idle fluctuates when it is cold indicates that the Fast Idle THermo Valve is out of adjustment.
This valve is located ot the front of the intake manifold on the driver's side just below the accelerator cable. To adjust it, wait until the engine is cold (best to do it first thing in the morning).
Remove the two screws holding the cover on and start the engine. There is a brass needle sticking up through a plastic ring that has two slots in it. With the engine idle fluctuating, use a thin flat blade screwdriver to SLOWLY turn the ring CLOCKWISE
until the idle stabilizes. Once done. put the cover back on withg the two screws and you should be done.
