Took my car in for a service yesterday and fuel system clean or service was due so got that done too. The tech did not tell me that these lights would be triggered before the service but then told me that it happens to all vehicles. Anyway he told me after 2 hours of driving it would go away. 4 hours of driving later they are still both on. I’m more concerned about the trac off than the engine light. I have a computer thingy should I just reset them both to enable traction control again. Pressing my traction control button does nothing.
