P0305, replaced plugs/wires and swapped coil packs, but CEL still there...
Any help would be appreciated with this problem:
My '97 4Runner 3.4L started stumbling and threw a CEL about half way through a long drive home, I limped home and checked the CEL, it was a P0305. I replaced the plugs and wires thinking this would solve it as they were due. The problem got better, but not fixed. Still stumbled and produced a P0305 CEL.
I then thought it must be a coil pack gone bad, as this had happened on my old '00 once. I cleared the CEL, swapped the #5 coil pack with #3, went out for a drive and produced a CEL again. When I checked it I expected the problem to follow the coil pack to #3 but it threw P0305 again.
I'm stuck what to do next, maybe it's the fuel injectors themselves? How can I diagnostically check them to see if the one feeding #5 is bad?
Thanks!

I went with Denso and NGK wires.
I checked the fuel injectors on the passenger side, maybe my voltmeter is off but #5 tested at ~95ohms, #3 at ~31ohms, and #1 at ~15ohms. Any ideas?
