The leads are quite fragile ( even pulling them off the spark plug has been known to break them ) and have been know to deteriorate and arc out especially at the plug end. Sometimes you can hear it, or see it if its dark
If its possible, substitute a good lead... IIRC cylinder two is passengers side front so you won't need a long one. I'd avoid trying to do a lead swap with other "good" leads already on the engine.... IMO you stand a real chance of damaging them trying to remove them.
