hello,

have a crx with b16a1, the idle surges back and forth between 1-2k rpms all the time. I asked this question before and some people said i might have a vacuum leak somewhere under the throttle body. well i looked today and took some picture hoping one of you could use photoshop or paint and draw a circle or arrow where i should be looking.

also any other pointers on what could be causing this problem.

heres the pics

 

what happens when you plug that little hole with your finger. if the car reacts the same , you have a leak some where

 

Are you running on a stock or chipped ECU? Also are you running an CEL's?

 

I can't see in the pics but check to make sure that the purge cut and map sensor vac tubes are hooked correctly. Thats what my problem was. Try turning the idle valve in also, sometimes if its out to far the engine will surge like a vacuum leak.

EDIT: And i can't tell you exactly whats wrong, but jebus foo, clean that engine bay

 

cover the entire throttle body with something, if the car doesnt stall you have a leak in your manifold
