Tpi missing/ rough idle
i just completed a rebuild of my 350 and got it fired up but it is missing in 1 or 2 cylinders. i have replaced the spark wires and made sure they are in the correct spot and the plugs, rotor, and cap were all replaced right before the build. any thoughts what could be causing this?

Re: Tpi missing/ rough idle
if they have sat dry for very long, some of the injectors could be sticking. start the motor up and with a long screw driver put the blade against the injectors and the handle against your ear.
depending on the injectors you have, some have a nice sharp click, some not so sharp. but they should all sound pretty much the same as each other.
if you do find 1 or 2 that isn't firing, with the motor running use a 1/2 or 9/16 inch wrench and lightly tap on them.
