I had a check engine light come on and took it to autozone and the code said this p0455 emissions leak (gross) and I just bought a new gas cap a week before thae light came on. I had got gas the night before it came on as well. I checked the gas cap and it was on tight. What else could this light mean? How serious is the light. I do not want to drive the car if it is unsafe.
