My guess is that the 57 is related to the LPG conversion. If the injectors are simply cut the injector Voltage code will set. Does the check engine light operate with the ignition on i.e. work?

The 76 may be due to a misfire (on LPG?) or a sign the the sensors are dying.

First step with codes, after noting what they are, is to clear them, drive and see if (and when) they re-occur i.e. whether there is a real problem or a rare event.
