Idle approx 5-6 hundred RPM . When I remove plug wire from distributor cap while running , driver side foreward and aft make no change while all otherscause engine to drop off worse. I have spark arcing to the affected wires , all actually . Swapped effected wires and plugs , no change.
Suspecting injectors ( but 2 at once ?) or signal to fire.
Are they easy to swap around for evaluation ?
Do they get a 12V signal to fire that I can read with a test light ?
