Intermittant spark

After my cam/head/header/tb swap, the right bank is running rich and the engine stumbles. Its obvious(?) that one of the wires on the right side is firing intermittantly????

What is the best way to diagnose which right side wire isn't firing consistently??

Check your wires and injector harness' (if 94+).

Hate to seem like a complete idiot, but i'm trying to figure out how to check the integrity of each wire without becoming a contortionist in trying to remove each one. Any ideas?

Also, what should I be looking for on the injector harness? Isn't there a tester commercially available, or is it feasible to test the resistance values to the computer?

Well since you just did heads/cam, you would have to pulled the harnesses off, check to make sure they're back in the right location. 93s don't matter, 94+ have a white number on the outside of the harness. Just make sure the wires coming from the opti are going to the according cylinder.
