I got a cylinder #3 misfire OBD code this past summer,was getting missing under acceleration with a jumpy tachometer, and I changed the coil pack, put in new spark plug but not the s.p. wire, because it looked okay. Problem went away....for a week.
I did the night time firefly visual test on the wires. No arcing, so I assume they are still good? Or is there no way to test them for good/bad?
Now I am getting missing for the first 20 seconds of cold start-up, and under acceleration, the dash flashed the service engine soon light 3 times and then stopped when I stopped provoking the problem.
Thanks for all your replies and troubleshooting advice.
