2015 Jag F-type Base - 35K miles on it, Just had serviced for 3, 6, 9 and 10 year services, including new plugs.

Stage 1 VAP Tune

I went to pass someone and pushed into it a bit, and got up to ~80 MPH, slowing back down to 60mph the car sounded a bit funny and the CEL popped on. I pulled over and a lot of very rich smelling smoke was coming out the tailpipe, and nowhere else. I limped the last two miles home with clearly misfire, ran the codes when I got home.

The car was low on gas, and my original intention was to fill up on my exit, it was 50miles to empty in the tank which I feel like has something to do with the codes. any insight or hints of what I can replace or fix though would be a god send! I'm a bit scared the tune might have been a bit spicy on the car and I'm a bit scared to tow it to the dealership, and now parked, wont crank. If i do take it to the dealership, should i put the stock tune back on it?

The Codes that popped:

P0300 (Random - Multiple Misfire Detected)
P0302 (Cylinder 2 Misfire Detected)
P0303 (Cylinder 3 Misfire Detected)
P1315 (No DTC definition found - See service manual)
P2237 (Oxygen Sensor Pumping Current Circuit Open Bank 1 Sensor 1)
P0087 (Fuel Rail /System Pressure - Too Low
P228F (Fuel Pressure Regulator 1 Exceeded Learning Limits - Too Low

I been driving an 1986 XJ6 for 7 years now and 80K Miles, i know my way around them under the hood mechanically for the most part. The computers throw me for a loop though.
