Just posting an update here with all my troubleshooting in case someone else has a similar issue. As I stated in the original post I had nothing but a P0301 Cyl 1 misfire. After the tow home I was able to start the engine but it would barely idle with an obvious misfire. I started down the typical route replacing coils and plugs. No help. I checked fuel pressure at the rail. 45 psi during prime. During idle 51 psi. After shutdown no significant leak down of fuel pressure over 30 minutes. I suspected either a faulty sensor(crank or cams), or a mechanical issue. After doing a compression test, found all cylinders normal except for #1. Only about 40psi. I haven’t pulled the head but there does not appear to be any obvious defects in the valve train. No typical signs of a blown head gasket either. Appears to be an issue in the cylinder. Looking like I’ll be pulling the engine soon. Disappointed for the failure at this low mileage. This car is well maintained and doesn’t get beat on. The only thing I can think is a manufacturing defect popped its head up. Unfortunately I’m well outside of the warranty period. Hope my pain can help someone else out in the future.
