My engine light came on this evening on my 2006 Pontiac G6. I took it to O'Riellys and they put it on the diagnostic machine. The code they came up with is P1174. They could not find in their database what that means. Would you be able to help me with that? Thank you for your time.

Re: engine light on
That code is for cylnder bank 2 running lean, there is actually an open technical service bulletin for this issue on your car, for clogged fuel injectors. That could be the problem, as well as a vac. leak, a malfunctioning bank 2 sensor 1 oxygen sensor.

check the oil and coolant levels. if coolant is low pull the sparkplugs and try to turn the engine over if still not turning free remove the serpentine belt and try again, if it turns over ok check the pullyes on the front of the motor to see if they all turn free by hand. a serpentine belt can prevent an engine from turning over if a tensioner, idler, water pump, alternator, or power steering pump is siezed up or starting to seize. being your battery is bad I'm thinking probably the alternator is seized. hope this helps mike.
first be sure that its the engine light and not the "service" light. the service light will usually illuminate if its time for an oil change. if its the service light ur owners manual should tell u how to reset it. if its ur engine light then try disconnecting ur positive battery cable for 1 minute. that should reset ur ecm and get rid of the engine light. if the engine light comes back on then have a diagnostic scan done to determine whats causing it.
