I was hoping someone might have an idea as to what is wrong with my pickup. Its an 84 with a 22r. I developed a miss at idle that clears up when you rev the gas and go. I was thinking maybe bad plug wires but they all passed the resistence test.

Thank you for any help.

 

A small exhaust manifold leak?

 

Thanks for the help but it turns out I didn't check plug wire #4 it had burned itself on the manifold.
