4age newbie having some idle issues. help!!

[honda_what?]

i recently got an 85 gts and the idle was pretty high when warm like almost 2000 rpm so i lowered it a little and last night night after a little bit of hard driving my idle shot back up to 2000 rpm.my idle control screw was backed off completly. could this be the acc? i live in pr so its hot here all the time can i just eliminate it??

maybe you have air in cooling system ... :wink:

Or an air leak in one of the hoses that connect to the plenum.

Sure sounds like the thermostatic idle-up valve under the throttle body.
Yes, you can take it off and make up a blanking plate to bolt on in its
place. Just make sure the air ports are blocked off, and loop the two
little water hoses. Set your idle with the idle air screw, and you will just
find that your hot idle is a bit higher than your cold idle.
