so, i have a fully built 2l motor from jeff at IB, runs great and everything except if i sit at idle to long, such as going through a drive through that has a bit of a line, when i leave, even just driving normal such as under 4k just accelerating normal, she puts out alot of whitish smoke, not for too long, sometimes just until i get up to highway speed and then it goes back to normal...anything i should be worried about or look into? could it just be im running pretty rich? any suggestions would be helpful!

 

no ideas?
