2011 Mustang GT Base w/ On3 Twin Turbo kit. Car starts fine. When accelerating, then driving - the first video happens.

After coming to a stop / idle, it goes away and you encounter the second video.

The OBD2 Code is P0155. Comes up as an O2 Sensor issue.

Just looking for ideas as to what's causing this to occur.


Video for detailed information:

 

Check the connection between the wiring connector on the back of the instrument cluster and the main wiring harness. You may also need to trace the wiring harness back from the instrument cluster into the engine bay and see if there's any problem with the wiring there.

 

Thank you, I'll check that out and report back with what I find.
