Rough Idle mixed with a P0300 SES code

Also, I seem to be burning oil. I changed my oil & filter over the weekend. It has not been more than 3800 miles since my last change. I drained about oil and appeared to have just barely 3 quarts in there.

If I take this into the stealership is the service covered under the Security Plus Vehicle Protection Plan? I did a search and it looks like possibly bad ignition coils?

If you have a warranty, always take it to the dealer.
