Terrible Gas Mileage !!
Long story short , I have a 2006 G6 GTP with 65000 miles on it, after a rebuild transmission ($2000). P0011 new camshaft sensor instslled by dealer $300 bucks !!New plugs and wires, oil change done, new air filter, new battery installed, I'm only getting an average of 200 up to 220 miles per tank !! And I've noticed a lack of power !! And ideas on what it can be ??? I'm thinking maybe thermostat stuck open ?? Or maybe I need a new catalytic converter ?? Or maybe the computer needs to be upgraded with new software ???
