I took my car to autozone and had them scan my car to see why my engine light was one. They gave me the code po401 and said it was my egr valve.
I had my egr valve fixed afterwords and my engine light came on 20 miles later. I took it into autozone and the same code po401 came up on their scanner. I took the car to a different mechanic today and asked them to look at the egr valve and tell me why it is still saying that it needs to be fixed. They said to not worry about it and everything looked fine and the light is on just because it is an old car. I am not comfortable driving around with my engine light on, but also don't feel like taking it to another mechanic and wasting money. What do I do?
