With 269k on the motor of the '00 V70R and a fluttering rpm needle at idle, I suspect my issue is a vacuum leak. So in preparation a little DIY tune up, I've decided to replace spark plugs, TCV valve, TCV hoses, and all of the other hoses I can replace.
Anyone know of any good tutorials/videos, or diagrams that can show me which and every last hose I should/need to replace? What must-have tools do I need to get? Any advice, help, recommendations I can get would be appreciated.
