Thanks for your help. I am not a mechanic, so would you please give more
detail? Which line
leading to cabin? Does that have someting to do with the idling and engine
performance? Or just
the noise from the dashboard?
PS. I changed air filter and PCV valve today. I seems better, but the
problem doesn't completely go away.
