I had a wierd issue pop up last night on my way home from work.
I noticed my truck running rough on the expressway. Next thing I know, my Check engine light was flashing. When I pulled into my driveway, I could tell it was not running on all cylinders. So I shut the truck off, let the truck sit, then came out about an hour later. Started it up, and ran fine for approx 10 minutes, then started to act up again.
Then I came across this post of the coil pack having rust on the bottom of it possibly causing issues.

I figured what the heck, let me try it. So this morning I took of the coil pack and there was rust. I cleaned it up, put it back. While I was at it, I ohmed out my coil pack to make sure it was good, and it was.
I started the truck, took it to work, and no more issues. Also went to Auto Zone to pull the stored codes and it said PO171 ( Bank 1 rich/lean condition) and PO302 ( cylinder 2 misfire).
Could the coil pack rust have caused this? Or was it just a coincidence that I moved it?
