So I changed my oil on Saturday and on the second time I cranked it over after that, the car started running on 3 cylinders. I had a P1399 and a P0301 CEL. I moved the cylinder 1 coil to cylinder 2 and then got a P0302 code. I moved the coil to cylinder 3 from 2 and got a P0303 code.

One of the coils died.

I have a MY2000 with 98,800 miles. I was dreading a possible injector problem like Random1 had or even a cracked retainer...

...just adding to the search database.
