My 92 dodge is smokeing white/greyish at idle. and it gets worse the more boost I run going down the road. I'm going to try bumping up the timeing. I'v read that it could be air in the fuel. I know I'v got one small fuel seep right at the pump on the inpute line. but how could air get in when my fuel pump is set with the 5-7 psi spring(I'v got a holly blue electric fuel pump). It has close to 300K on it.
