2006 Mustang GT fuel mixture too rich
I have a 91 Octane Predator performance tune installed. It is the correct one for my CAI and everything has been working great for a few months now. All of a sudden I have been receiving trouble codes indicating that the fuel mixture is too rich, (P0172 & P0175). Could this be a result of the outside temperature? It has been around 30 to 35 degrees Fahrenheit most days lately. Perhaps the mixture is too rich when it starts and runs cold for a bit?
What are the dangers in running with a fuel mixture that is too rich? Can this damage my engine? What can I do to remedy this situation without reverting back to the stock tune?
Any help will be very much appreciated.
