Don't forget to try the jumper wire too. The fact that it didn't flash my clamp-on timing light reliably and coil+ voltage was low (6 V) suggests an ignition problem.
YES! I'm going to do this after I get the gaskets on. Once I can rule out Vac leak and the issue is still there this is the next step. Although I have slapped a timing light on it lateley and its been fine.
Of course this all depends on the rain today haha.
