id still swap those injector connections though. Just switch 6 and 8 connections and see what happens. Just don't drive it like that unless it seems to fix the problem

Will do, Can't hurt to try thats for sure.

My suggestion wasn't to switch the injectors themselves. Switch the pigtails that come out of the harness and hook up to the injector. Put the pigtails from 6 on 8 and vice versa. Literally just unplug both connectors and pkug them into the other Injector

You may have crossed wires causing a misfire on only one cylinder.

impossible. you can't cross ONE wire. has to be at least 2 meaning you will have at least 2 misfires.

when I got my 93 (no longer have, wrecked badly) it came to me with #5 and 7 injector pigtails crossed from the PO.

Depends on where they are in the firing order, donnit?

I mean, yah, both cylinders fire; but only one misfires because the OTHER one is on exhaust or some such.

Ralph in that case you might have a misfire on o e cylinder while the other cylinder might be considered dead.. I think.... Depends on where the switched cylinders are in the cycle
