well i just hooked the two vac. advance lines into the front of the carb. the two from the trans to the intake. where does the one from my master cylinder drum go to and i thought the pcv goes in the front of the carb. i dont currently have a heater core hooked up so i ran a hose straight from the waterpump into the intake is this ok? also the truck dosent really want to idle what could cause this? i have also never changed the filter on my fuel pump could this be my prob?
