Just went through this maintenance myself, yesterday. Car threw a couple of CEL codes, one was misfire upon cold start and also a bad intake manifold. Dealer said manifold is covered under warranty, but had misfires in cylinder 1 and 4 due to carbon build up and had to pay for the cleaning...car is almost at 41k
My local shop suggested an oil changed after the decarb, but the dealer said it's not needed. Who do I believe?
