checked on data logger that we have, and I'm sort of new to this one...
need help trouble shooting and haven't cranked it since I cleared the code, my gut just won't let me do it, so before I do I just want some input.

code: P0303 clyinder #3 misfire detected
code: P1399 manufacture controlled ignition system, or misfire

Any positive input would be very apprecitated.

 

any tech's know?
