3.4 V6

1994 Pontiac Firebird • 6 cylinder 2WD Manual • 140,000 miles

I changed the spark plugs and wires, when I replaced the wires I did not replace them the way I took them off, now the car is not running smooth like it was at first, it stumbles, I need to know which wire go's where, or the firing order or something. I marked them with tape prior to changing the wires, put the tape fell off. Only ones I have right are the first wire and the fifth.
Need help
