CM2350 Injector Driver Codes

[Rawze]

what is the engine ser#?.

If the nuts on top of the injectors were not torqued properly, the injectors can be damaged internally... or nuts can come loose.

If the connector going into the valve cover has fuel or oil on it when installing it, false codes can arise.

If the Exhaust pressure sensor (or its feed tube) s not working/reading properly, or is an after-market branded,.. or is a chineesium fake.. then you will get injector mis-fire codes.. but not so much coil codes.

just some random guessing.
