My '05 Envoy Denali 5.3L threw a code today. Called OnStar, they said it was P0171. Cleared for now by disconnecting battery. What is that code and what causes it to get reported?

Threw a codeylab 02-07-2006, 04:37 PM Bill, its O2 sensor bank #1 too lean. - Hey, but its not a miss which would have caused too rich and deactivation of that cylinder. Try cleaning the MAF sensor....its most likely gummed up! (That or you have a vacuum leak). Ray Updated: Note to self, check spelling before hitting post!
