makaGT

I have a 2002 GT thats misfiring during acceleration in all gears. it seems to idle a little rough till im at a complete stop. it also smokes a bit(white). I was also told that most of the issues with this engine is the fuel rails. i have no codes(read with Predator Diablo).

118k miles
mods:
k&n intake/filter
headers
exhaust w/deleted cats
4/10 gears
msd coils

i also tried to reset the tune with the predator and still nothing. any assistance would help thanks MF.
