REGURU

Both the coils & spark plugs were replaced about 10k miles ago and a little over a year. Dealer said they checked all the coils and said they all looked fine. He then said it must be the sparks, pulled them and said they looked fine. That's when they said it must be the fuel and tested it. A little light, I don't know what that means either except they said they weighted it or something. All seems silly, but thought I would let them rule that out and check with you guys since you know more than the dealers.

As far as shuddering it only happens when cold and going pretty slow, after that all is fine.

I would be looking at fuel pressure really close, id be thinking its a little high at idle, or maybe un steady.

So I got my S back yesterday and they said the new gas did the trick, no more codes. Still feel like it is running a little ruff this morning so they may have just given up. I will see if it gets any worse and then take it to and indi shop or a different dealer.
