Not Pontiac, reset Fuel composition sensor on 2013 tahoe?
hey gang: having a cold start issue with the Tahoe...investigation seems to be fuel rich situation... Adding some air when starting helps out.
I have an innova 5610 OBD2 reader...shows Long term fuel trim at -25% and fuel compositon sensor at 65% Alky. According to research, the fuel comp needs to be reset since there should be no more than 10%, causing fuel rich condition. This OBD2 scanner has no rest function for the Fuel comp, at least not for a tahoe they (innova) say. Any other way of doing it? pulling the connector on the sensor or battery? George
