2002 ford taurus DOHC engine codes P0305 P0316

I have had the check engine light come on for a few days then go
off for a few days. don't really know what the problem is.

codes report misfire on cylinder 5 and a crankshaft position
censor. Don't know how a position censor could pick one
cylinder to fail on.

I changed the spark plug same problem

swapped the spark plug wire pair (1 and 5) from the coil to see
if part of the coil is the problem and cylinder 1 would fail now. didn't
stayed with cylinder 5

Has anyone had a problem with the Crankshaft position sensor.

So the P0305 is solved??? It sounds like it???

To my knowledge P0316 is Engine Misfire Detected on Startup (First 1000 Revolutions).

So where are you at with the issue? Did you replace the #1/5 coil/wire yet? It sounds to me like if you fix the single cylinder misfire then you're all set.

Just swapped plug wires? How will that determine if the coil is bad?

Swap coils with another set of cylinders and see if the misfire follows.

If it does, there's your problem.

Good luck and keep us posted.

The Duratec uses the Coil-On-Plug design. I had a 2000 Taurus Duratec, nice car
