A can of Sea Foam in the tank and new iggy points and she is better. Sort of.. The tach jumpiness is totally gone now - must have been the points. But she is now missing on a couple of cylinders. Pulling the injector plug wires one at a time and watching the RPMs told me that two of them are not firing all the time. I thought Sea Foam would clean that up, not make it worse. Or maybe this is electrical after all. Looks like I need to pull the injectors and see whats up there... Thankfully, this will be a long weekend!
