I have a 1986 Pontiac Sunbird that is missing out and backfiring. I have
changed the spark plugs, wires, and distributer. I also messed with the
timing to no avail. It is still missing. I am now thinking it is in the
vacuum. Does anyone know where I could get a free diagram of the vacuum
system? Any suggestions?

sounds like crossed spark plug wires. recheck that you put the wires
correctly on the distributor.
