Re: Maz's 2013 DGM STI
Had an ancient lady take a left hand turn from the main drag onto my road while I was pulling up to the stop sign and she decided to turn into my lane (opposite direction) and I had to take emergency actions which resulted in my car promptly throwing CEL / P0031.
Recognized that code as the O2 sensor (not the first time), suggesting maybe my wiring was a bit loose. Took two reflashes and looked through the engine bay but everything seemed ok. Got it to go away for now and stayed away for a day. Will keep my fingers crossed.
