Before the new plugs, it was only cylinders 3 and 4 every time (and I reset the codes 3 or 4 times)
Then I replaced all the plugs and I switched the #3 and #4 coils to the #1 and #2 spots.... and now I still get a misfire code from #3 every time, and occasionally #1 and #2, show up also... So, I'm wondering if I have a couple coils going bad, and one injector in the #3 spot.

That would be nice if it were that easy, and simply replacing the pump, but that wouldnt be my luck!
I guess we'll find out what the dealer finds when I take it in, either tomorrow or Monday.
