Check the oil lately? Checked to see if it's being pumped?

Which cylinder is knocking? If the front pull out the spark plug and check the combustion burn, the tip should have a tannish tone on it.

Have you checked to see if it's throwing out a code? Talk to the service department at your local dealer. I believe it tells you how to check for a code in the owners manual.

With the little info you offer I am guessing you have an intake manifold leaking air and the ISC is trying to compensate .

As a test , spray some brake cleaner where the manifold meets the heads while it idles . If it stalls that's because it sucked the brake cleaner in through a leak .

Adjust idle screw.

sounds like that mini-mart regelar is catching up with it ..
