L92 error codes???? I had my AC Cobra in a Cadillac workshop, they found following error codes;
PCT
P0171 Lean bank 1
P0174 Lean bank 2
P0131 Low voltage bank 1 sensor 1
P0137 Low voltage bank 2 sensor 1
When we had the Tech 2 unit connected and ran the live plot on the O2 sensors it looked fine and suddenly they went flat. After some time it corrected itself again.
What could this be?
