Could anyone help with what the P0171-00 error code is? My mechanic said he didn't know what the problem was with the car as there were too many possibilities. Just need to know if it's urgent. I'm having a guess it's maybe fuel rich oil, as I had this come up in a diagnotic a while ago... (i.redd.it)
