Took the 1998 Boxster out and the CEL lite up within the first 100 yards, multiple codes where read. Car did not want to exceed 2000 rpm. Turned around and put it back in the garage.

PO 300 - Misfire Detection
PO 304 - Misfire cyl 4
PO 305 - Misfre cyl 5
P1 316 - Refer to Manual
P1 317 - Refer to Manual
P1 319 - Misfire Detection

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.
