This is not a 911 issue , just asking for opinions. Went to the stealer today due to an issue with the factory security system. Got the code 1631 , replaced the ignition cylendar ( wasn't reading electrical current properly all the time & was causing the fuel systm to shut down to prevent theft ) . On the good side I got to see my balance rates for free !!!! They range from -2.7 to +3.1 at idle & warmed up !!
