βI had a CEL come on out of the blue (solid, not flashing) along with the VSA light, and the triangle with exclamation point warning. I was able to baby the car home.βView original
βI arrived & started the engine to see if it could be moved in what I assumed to be limp mode. I drove (very low power, missing badly, stalled once at a red light) a few miles to the shop & read the codes (Blue Driver).βView original
βI ran the codes and have a P0303, so i decided to take it to the shop. By the time they got to it the engine light was off again, they still ran a test to see if the car misfired and so far it was 0.βView original
