Idle Valve

[kique303]

So Im having problems with my car I thought it was the idle valve so i purchased one from ebay and replaced it myself but it made no difference my rpm meter keeps reving up and down makes that annoying sound and some people told me it might be the o2 sensor, or the map sensor any suggestions i have an f22b1 swap. thanks

is your antifreeze full? mine did the same thing untill i put some antifreeze in my radiator and it stopped

There are many reasons that this happens.

1. Balance shafts are not properly timed
2. Fast idle valve is backed out to far and allowing to much air in or not enough
3. Idle air control valve is not working properly
4. Vacuum leak on intake
5. Throttle is not adjusted properly and allowing or not allowing enough air in the throttle body
6. O2 Sensor will cause this problem also causes surging when idling or driving
7. Maybe something else....

What all have you checked so far? Usually everyone says it is the idle air control valve which in most cases I have found it is not.

Let me know

Also in case you all are wondering why the idle is fixed by putting more coolant in it is because your fast idle valve is thermally controlled. It has a coolant line that goes to the bottom of it and when the car reaches operating temperature it moves the valve. Low coolant will not allow this valve to move thus idle is all over the map.

thanks for the tips Ive replaced the idle control valve checked the radiator for coolant and the o2 sensor but thanks I'll check the other stuff out its crazy what little things can make your car go bad

Hey man thanks turned out to be a vacuum leak on my intake and my throttle wasn't adjusted properly got the problem fixed thanks

hoses

MAKE SHURE THE WATER HOSES GOING TO THE IACV ARE CLEAR.If they are not then it wont work.

where did u have the leak at...im experiencing the same thing

Where the intake goes into the throttle my car has an f22b1 swap I bought the car like that but when they did the swap they left the same throttle body and map sensor it worked at first but with in time it messes up so I got everything original for the engine.

Yeah man thanks I did check those hoses
