Car is running a little rich and my IDLE is weird

[regnaleb]

Hey guys, ive checked all over the internet but i need a straight answer to my specific problem, hope you all can help me Im relatively new as this is my first sr20 ever owned..

So ill start with my setup, its a s13 sr20det with a front mount, a walbro fuel pump and a stock ka24e maf. The problem which i think lies in the new BOV i bought recently. Its a Tial 50mm "Q" edition. Its a non-recirculating BOV i believe and it has a 11psi spring. Here is a link to the specs http://www.tialsport.com/index.php/t...ovs/46-tialbvq

Now, ive heard that people with sr's usually run non-recirculating BOV's to get the pfffshh sound and such. But because of that, my engines getting more fuel than the air that is lost through the BOV opening. So what gives, how do i fix this?

The idle problem i have is this.. It idles fine to begin with, nice and steady but the problem comes when i play with the throttle. The needle will rise accordingly to the peddle but when i release it there is a brief delay before the needle drops. Its not very responsive. And after that, with my foot off the throttle, the needle sometimes doesnt go back to normal idle (1000 or so rpm) it will hang at say 1500 for a couple seconds and then suddenly drop back to 1000. Im not too sure if both problems lie in the bov...

So yeah... please help lol Thank you
