Codes p0316 and p2270

[slow poke]

Guys,

I'm throwing those 2 codes as of today, noticed the passenger side downstream o2 had ripped wires last night during an oil change. Could that cause both codes?

I'm lund tuned, no cats

• Diagnostic trouble code (DTC) stands for “Engine Misfire Detected on Startup (First 1000 Revolutions).”
• The code is logged once one or more of the engine’s cylinders misfires during the engine’s first 1,000 revolutions.
• Code P0316 is often logged with other P0300 series codes that are associated with the misfiring cylinder/s.

• The powertrain control module (PCM) will log a P2270 trouble code when it detects that the #2 oxygen (O2) sensor on bank 1 is sending signals pertaining to a lean fuel mixture.
• A faulty O2 sensor or an exhaust leak can cause diagnostics to log this code.
• There are no other symptoms for this code except for an illuminated check engine light.
