Hi,
If you look at pics 1 and 2 below, they provide the vacuum information. However, I have a question. If the misfire started after the work, are you sure one of the new spark plug wires wasn't mixed up or damaged?
If you look at pics 3 and 4, they provide the firing order and spark plug wiring. Check to make sure they are in the correct order.
Let me know.
Take care,
Joe

Hi,
Thanks for letting me know. Have the vacuum schematics helped? Did you find any issues with the hoses?
Let me know.
