ok here is my prob i have had an idle prob for a while now. I finally figured out what the prob was. It was my fast idle thermo valve.. now from the way i see it there is a thermowax plunger in the valve that unwinds, when that unwinds that is when i get the idle probs. so therfor i wind it back up as tight as i can, but it seems to be that it is faulty cause it keeps unwinded cause the idle prob again. Now if the fast idle themo valve it no good anymore i have to replace it right. here is another question that i have. My car is a 96 accord ex that is having the idle prob. I also have a 93 accord se that seems to never have that prob. are the fast idle thermo valves the same where they can be interchangable saving me some cash. please someone let me know

 

so i guess no one knows if i can interchange the fast idle thermo valve.

 

The part numbers don't match, so they're probably not interchangeable.

Honda never reccomends that you try to fix a busted fast idle thermo, they just say to replace it in any service manual I've ever read.

 

do you know whats the price on something like that
cause mine is totaly ****ed up

 

$54.05 plus shipping from www.hondaautomotiveparts.com. MSRP is $72.04.

 

can i ask you a ques about it. how come the waxplunger in the thermo valve unwinds the way it does and i get the idle prob

 

When the engine is cold, the thermowax (which is surrounded by coolant) contracts. This opens the valve which is attatched to a bypass in the throttle which gets more air into the motor with the throttle plate closed, thus raising the idle speed. Once the motor warms up the thermowax expands again and closes the bypass.

The thermowax should be unwound when it's in coolant that's at normal operating temp. If it's unwinding before the motor warms up that's your problem.
