Why is my intake and throttle body have a ton of oil in them

if the oil is fouling the top of the plug wells where it connects to the coils and the bottoms are dry other than any oil you’ve got in there by accident then I would take the top off and replace the full gasket.

If the top of the plugs are dry but the tips are wet and the cylinder chambers are fouled with oil then it will either be piston rings or valve seals gone.

Fixing the camshaft sensor may sort the issues out with the engine shutting off but obviously not the oil, if oil is getting into the cylinder chambers then take the car to a garage and get them to perform a leak down test to check the compression and if there’s any issues there that is causing the oil to get in as that will be the most expensive repair if needed, I would also get the timing checked at the same time if the sensor was out just to be safe especially if the mileage is creeping around the 100k and is a chain. If a lot of oil is getting into the chambers then it will probably be this stalling the car rather than the sensor because you wont be able to get a good enough spark. hope this helps.
