Truck runs rough after a Spark Plug Change
#21
If you have verified that the plug wires are routed correctly, then I would tell you to go back to stock plugs. Since you changed the plugs, which developed these symptoms, then that's the root cause.

so - do you think he had a bad plug, or a bad gap, or a loose plug, or loose wire in the autolite install; or do you think there is actually something inherently wrong with the autolites and that the champion plug is actually different ? my .02 is that all plugs are all pretty much the same and he picked up a mysterious defect in the original plug swap. this is a good reason for only changing one thing at a time - in the event of a problem, you know what to address.

Not necessarily Autolites in general, but I have seen repeated complaints on here about Platinum plugs in general.
Iridiums seem to be fine, but they are even more expensive. Last a lot longer though. My previous set were stock-type copper NGK V-powers, and now I am running 3923s. I noticed that occasionally, especially when cold, the truck has more hesitation when i step on it with the 3923s. Also seems to have lost a little bit of "snap" during acceleration. Champions are up next.

About 13 years ago, I had a 1993 Ford Escort wagon with the 1.9L that I swapped to platinum plugs. It ran great and could even get 400 miles to a tank of gas with the A/C running.

I'd put a six-pack on the bench and say that if he swaps out rotor, cap, and wires on the working plugs without problems, throwing those Autolites (if they're not actually in some way broken) back in won't introduce any new problems. I could be wrong, but I'll bet the price of a locally available sixer on it.
