CEL and VSC lites came on oneweek after purchase of 2007 RX350 64K. Showed error code P0354.(If yours shows same you are in luck.) Ignition coil D is culprit here. It's the front center coil. Good news-your WIFE can replace it (Would also suggest replace spark plug at this time) Remove engine cover. Disconnect clip attached to coil. Pull off faulty coil. Remove spark plug (5/8 socket) Install new plug(use anti-sieze) Push new coil onto plug (use dialectic grease inside boot) Re-connect clip. You are done. 10 minutes. Both lites will go off.
