Six cylinder 3.1L engine two wheel drive automatic.

I just changed spark plugs and my car now is in rough idle and sputtering. I used Autolite platinum. I want to know the spark plug order. I numbered my wires and I may have messed it up. Is it -2-3 along the fire wall with 1 being on the passenger side? And 4-5-6 in the front with 6 being on the passenger side. I assume that is to correspond with the numbers on the distributor cap.

Last time I changed plugs I changed wires.

The part that says front in the diagram is passenger side. You have a coil pack, no distributor, correct?

JDL,
Thanks for the diagram. I had two and four switched. Yes, I have a coil pack. I mistakenly said distributor, also working on my old gas tractor.

Have a century with 3.1. OBD-II says #6 cyl misfire. Looking at the engine from front of car, which cyl is #6.

Towards the firewall, the plug wire is broken. Again, it is the firewall side of engine, furtherest on the left near alternator.

I think this is #5 so why is it showing #6 misfire. A diagram would help.

Since it is not my car, I don't want to buy a manual.
