Only way I found out was the dealer checked the code from the CEL, plus visual inspection, and diagnosis came back to broke IACV, and broke PCV. You can easily see the IACV from the front of the engine bay, and looks like would be a quick fix.
but then again, this diagnosis was confirmed from the CEL error code... maybe best to get a specialist to take a look.
