car smoke just when i get off the gas but when i punch it there is no smoke

 

a little more details..

you run it up 1st, up 2nd and half way through 3rd to like 5000rpm. then you let off the gas 100% and then smoke comes out of exhaust pipe? then you punch it again and nothing?

what colour is the smoke?
