sputtering 12v
 

Got a stock 12v 1997..starts and idles fine has a slight sputter from idle-1100 rpm or so when you press the fuel and puffs black smoke imediately...puff just a little blueish white smoke when you let off the fuel???

anyone?

Im thinking you may have an injector crapping out.

is there a way i can test the injectors

Start small.. try changing out your filters before you go pulling injectors, injectors have to go to a shop to have'em pop tested..

thanks but i went ahead and sold the engine,truck was wrecked and the intercooler tubes were all bent up.The buyer seemed to think that was the problem

seems like air in the lines or a bad injector pretty cheap fix
