Is the car running bad???
What does the #2 plug look like strap/electrode?
The best thing to do at this point is to replace the injector for #2 if that one had gas all over it. Otherwise put the 24's back in.
maybe its pouring so much gas into that cylinder that the gas is making its way to the end of the pipes still in liquid form! lol, smell the liquid comming out of there! not too much though
try and be more specific on the color of the smoke too, all those colors could be anything! good luck.
