I have a b16a with a ctr intake manifold and throttle body . Just the other day I started the car and the idle jumped up to 3000 rpms. After I allowed the engine to warm up the idle went down to about 1900-2200 rpms and then after driving the car for about 5 minutes the idle was fine 700-800 rpms. I believe that it is a bad idle sensor but do not know how to check. Any information, diagrams, ideas would be great, thanks.

 

never mind I took apart the fitv under the throttle body and screwed in the white screw and it all cool........................
