I have a 2010 RX350 and when I went for an oil change, I also got a diagnostic because I had the (check engine, VSC and Trac off) lights on for awhile now.
So based on the diagnosis, they recommend replacing the manifold.
Quick question-the part # is 17140-0P150 for the manifold that needs replacement. Does Bank 1 or Bank 2 make any difference? And is it the driver side or passenger side?
