1991 Chevy 1500
So i just had my "new" truck emission tested as per Indiana. I failed my HydroCarbons. I know that its unburned fuel going through the exhaust. I just replaced my plugs today and my air filter. I plan on changing my Wires and Cap/rotor tomorrow. What else can i look at that would cause that?
