Haha yeah hadn't taken the time to post here! Anywho, picshow about the pics you sent me. lol resave from messenger!
Pretty sure it's not a leak... It might be that that the stock manifold had this small chamber for the idle air prior to entering the manifold it self? Not sure... also I tried a brand new idle air control valve from a friend (probably an ebay one) and it ran just the same... I'm pretty lost on what it might be to be honest :$Maybe a leak? I don't think the design would do it alone
Wouldn't really be a big secret, but still, I honestly don't know as my friend putted most the work into it... I'd guess somewhere around 250-300$ but honestly I don't knowJust curious if you want to pm me, how much would it be to make one? Same shape and all, I would use it for a NA rally car
