5 error codes at once
Greetings,
So the CEL came on yesterday and I had autozone run the codes. What came back was p0401, 2 p0171, and 2 p0170.
I have research what each one of these mean but what I was wondering is, what would cause all of these come on at once? Any help would be greatly appreciated.
So before I get yelled at about searching, I have research each one but need a cause for all at once. Wasn't able to find someone that has had all at once.
Thank you,
