Fixed ignition problem: Paranoid follow-up question.

My 1996 v6 started stumbling/shuddering at lower RPMs. This would go away as the truck warmed up but it got progressively worse day-by-day.

At first I thought it was a drivetrain problem but I tracked the problem down to either fuel delivery or ignition problems. It turns out that the contact between the ignition wire connecting #1 coil to the driver's side cylinder (4) was corroded and making poor contact. It wasn't a regular enough misfire to give a computer/diagnostic error (which made it hard to diagnose). However, it became obvious because, eventually, there were occasional visible sparks from the coil/wire contact to the engine cover.

The solution was replacing the wire ($70-ish for all 3 at AutoZone) and cleaning the contact on the coil. I checked the coils, changed the plugs, and cleaned the throttle body while "in there".

Anyway. As I removed the ignition wires, I noted the connections and I drew a little diagram so that I would have a reference for putting them back properly. Being overly anal, I doublechecked my diagram with online manuals (from forums, AutoZone's website, etc) and I found that these disagree with my diagram. The proper connection is 1-4, 3-6, 5-2, right? I installed it this way and it's running wonderfully. However, I'm a little concerned that it had been hooked up wrong since the last time anyone messed with the wiring which, for all I know, could have been someone on the assembly line 150,000 miles ago. It's more likely that it was hooked up correctly and that I just got my wires crossed (har har!) and screwed up my diagram. I just want to make sure.

TL;DR: If the ignition wires were hooked up wrong (say, 1-4, 3-2, 5-6), it would obviously run like shit (or not at all), right? Because two cylinders would be firing at the wrong point in their cycle?

Thanks!

 

It will run if firing order isn't right, but not good.

It would probably backfire at start up or during operation. The computer might kick in and back it off due to the knock sensor,,but it will still run horribly,,and be easy to see and feel.
