Definitely have a spare crankshaft position sensor and RCM. The camshaft sensor which I’ve seen be a problem in these cars almost next to never is your choice but they’re considerably more expensive like 3X more than crank sensor and you’re already buying a RCM. I would spend that money on DJ’s refurbished RCM. His refurbs are better than new IMHO. I’ve seen brand new RCM’s with solder points that look like a child did them.
