I am a believer in repairing/changing one thing at a time. If you replace your ignition components and fix your vac leak at the same time, you will not know what caused the problem.

Look for the right angle fitting at the intake manifold between the engine and the firewall. That fitting is hard to see and hard to access when you find it. It resides in an area of high temperature and may also be coated with oil. It is usually the first to go because of that but is also the most overlooked because it is so hard to see.
