Question Crazy idle... why?

my 93 civic ex coupe will start up at 3000rpm (which is too high)and when its in neutral it jumps from 1000rpm to 2500 rpm (which just sucks) everyone thinks i want to race when it wont quiet down any... what could the problem be other than a vacuum leak somewhere? any ideas? thanks!

FITV, tighten up the plunger

You can check it by following the helms, put your thumb over the hole

Finally a correct answer. It is most likely this part. Fast idle thermo valve.

it is on the underside of the throttle body... and there are 3 bolts holding it in.. the valve (plunger) gets stuck shut, and you can replace it, or try and unjam it/tighten it (like transzex said)

it isnt hard to get to at all! get a small sized 1/4" ratchet and wrench, find the best way to get to the 3 (10mm) bolts, and loosen them up.. pop the valve off.

before you do this, you might want to take off the coolant line that comes off the intake manifold and goes to the valve.. plug the nipples, and start the car.. if this eliminates the surge, then the FITV is your problem..

a lot of people fabricate a "block off plate.."
i think the best thing to do is fix it, or replace it..
