Car ran great the weekend before without issue. Plugs changed within the last 1000miles, EOS replace within the last three years and O2 sensor was replaced on drivers side ahead of cat last fall. Car has 46,000 miles. This car has had no modifications, any help would be much appreciated.

If my information is correct all the codes are misfire codes.
P 1316 and p 1317 are also for cyl 4 +5.
I would start by pulling the plugs and cleaning them on cyl 4+5 and also look very carefully at the coil packs on 4+5 if they have any cracks even if they are hairline cracks they could be the issue.
let us know what you find.
