Start by going through all grounds first. Remove each one, clean then reinstall. Replace any that are in questionable shape. Grounds-Grounds-Grounds The importance of good grounds.....

Clear codes afterwards and see what, if any, come back

Ive Been through all the engine grounds found the alternator wasn't charging swapped that out left the batteries off overnight and codes 17,18,49,62 are back dtc35 has disappeared but I have noticed when I start it on the odd times it revs up real nice then it develops a sort of rough running scenario and when revved it backfires or pops I'm starting to think broken wires from the install but I'm not 100%

A problem with the 5v. circuit can cause all those codes.
