Hi all, I'm new to the forum, and fairly new in general to working on my Ranger. I've done oil changes for years but have recently stepped up to slightly more complicated work, so my apologies if my question is stupid
I have a 2001 Ranger 2.3L with about 110K on it, which was recently running hard. Based on what I could find on the forums and elsewhere, it seemed like a misfiring cylinder, so I decided to do some work on the ignition, specifically replacing the ignition coil, plugs, and wires, all of which were original to the truck (I think, given that the original owner doesn't seem to have replaced anything, ever).
I purchased an aftermarket ignition coil from AutoZone and when I was installing it and preparing to re-attach the plug wires, I noticed that the firing diagram on the coil is different than the original.
The OEM is labelled:
(This is how it looks assuming that you're standing at the front of the truck looking under the hood towards the back)
The aftermarket is labelled:
I re-attached the plug wires based on the diagram on the aftermarket instead of the exact positions from the original and when I started the truck up, it knocks REALLY bad, which it didn't do before.
So, after all of that (sorry for being long-winded), should I be attaching the wires based on the original position or based on the diagram on the aftermarket?
I'm not sure if the aftermarket would actually have a different firing order or if maybe the label is designed for a more common setup than what my Ranger has?
