90 hatch with b18a1, not sure why its idling at 3k when cold. any answers?

 

does it idle at 3k when its warmed up?

 

idles at like 2 through 2300 when warmed up and in neutral

 

Is your throttle cable properly adjusted. Sounds more like a vacuum leak. When did you notice the idle?

 

Make sure the idle screw is tightened all the way they come loose very easy just use a flathead screwdriver its on the throttlebody. if thats all the way tight unplug the iacv on the back of the intake manifold while the car is running if u unplug it and ur car is still running you have a vaccum leak. Hope this helps pm me if u have any questions

 

options you got your idle screw is really loose
2.vaccum leak somewere in your lines or the manifold
3 your temp sensor is unplug or its bad

pm me if any questions bro but it should be an easy fix

 

I thought it would be the fast idle valve but that **** is hard to get too. One day like 3 months ago it just revved past 3grand

 

Bought to try and do that today will pm if it still idles high
