Put wires on correct plugs.

What kind of plugs? Torque specs are 13lbs and coil packs good?

If they were Autolite, that could be why... lol
Otherwise, make sure you plugged in all the electrical connections and vacuum lines correctly...

Didn't possible break a plug on install?
A piece of dirt or carbon caught under the plugs seating area in the heads?
Gapped plugs properly?
All wires properly plugged back in?
Can you make a short say 20 or 30 second video of it running, and post it.
