New plugs/wires, truck now misfires...
2004 Ranger 3.0, had a miss on #6, truck has 100k, replaced all plugs, wires & coil. Gapped to .056.
Truck now misses badly, gives errors of miss on 1,3,5 & lean on one bank (forgot which). Traced wires multiple times, no dice. According to all sources I can find, cylinder number order goes like such.
front >
654
OOO

321
On the coil it goes like such:
465
OOO
OOO
321
Has anyone ever had this problem, and are there any Rangers with an alternative firing order?
Cheers!

I found the problem, which was pretty unique...
The engine is timed 180 degrees out. I realized when I had replaced the plug wires that I had pulled them from the wrong side of the coil, and swapped them later thinking I had messed up. I hadn't. My coil is wired exactly opposite the diagram, hence the reason it wouldn't run.
For those not familiar with it, you cannot install the coil backwards by accident. I purchased the truck 2nd hand, but it only had 30k on the clock so its rather unlikely to have had that kind of work before I got it. However, also unlikely that the factory would send out a truck like that, but...
Hopefully nobody else will have this problem. If you do, now you at least know its a possibility.
