2001 pontiac montana, 4.0 v-6 what is the spark plug order, I think...

...someone has crossed a wire as it misses? I had this engine tested at Auto Zone and needed to change rear oxy sensor,which I did. It still misses and service engine lite still stays on. friend said the spark plug wires may be crossed somewhere but don't know the spark plug order. any body know the order.

1-3-5 are next to firewall
2-4-6 are next to radiator
Coilpack should have numbers labled on it
coil-pack left to right 5-2-3-6-4-1
firing order 1-2-3-4-5-6
