its a 92 accord with the f22a1 and the car should idle ROUND 600-700 RPMSbut its climing up to 1500 rpms and drops to 1000 and repeats unless i put on the A/C whats goin on

 

sombody say something

 

might be ur map sensor or ur idle control senser

 

thanks

 

anybody esle got input?

 

does this car have a iacv (idle air control valve)? if so, it could be dirty and in need of a cleaning or it may need to be replaced. do you have any vacuum leaks? this could include both gaskets and hoses, which are cheap to replace, whereas the iacv is not, if you have one.

 

ive seen it from the Idle air control valve (IACV) or the Map (mass air) or the valve under the throttle body... Cant remeber the sensors name...

i had to do them on a few of my accords... allot of civics have the same problems..

 

first thing to do is start the car and block off the throttle body with your hand and if it continues to run start lookin for a vaccuum leak if not I got 50 bucks on fast idle valve its the valve in the front of the I.M. with 2 vacuum lines coming off of it, or it could be the electronic air control valve on the front left of the I.M.

 

oh and when i get the car above 30 the car will idle at 1500 and stay there untill i slow down under 25 it will start to do what i stated earlier

 

Check the tps sensor( throttle position sensor), timing could be off, or the idle air control valve. Clean the screen out. Id also consider taking off the intake manifold and checking for cracks. If thats not the problem maybe when you put it back on it was the gasket all along. If thats not it. VACUUM LEAK. Replace the little hoses that connect to the mani.
