Welcome to the site - you have posted in the right place.

P0136 O2 Sensor 2 Circuit
P0607 Knock Sensor Signal Circuit
P0300 Misfire detected at low fuel level
P0302 Cylinder 2 Misfire Detected
P1230 Main Relay Stuck Closed
P0571 Brake Light Switch Circuit Incorrect Signal

Which is the oil cap on the bottom of the engine??

Does the engine have a misfire?

The knock sensor code can come up if there is a misfire or the engine has been run low on oil (possible if driven with the cap off).
