My 2006 B9 Tribeca has developed an idle misfire anytime the RPM is below 1500-
Anything above the 1500, engine smooths out and runs good.
Once the engine gets up to operating temperature - you can let the engine throttle back to idle from a high idle and engine will die when the RPM drops and will not recover to idle.

Any advice on what my next step should be?
