P0171 - po174
So I changed my oil and adjusted my catback on saturday and as of yesterday I have these two codes 
After searching it seems that it could be a few things but I dont see how after I did some routine maintance it would affect me.
The car throws the codes within 5minutes of startup and also seems to idle high at start but it does come down.
What should I check?
