2002 cadillac escalade trouble code p0171&p0174?
i keep getting these trouble codes every two weeks, replace fuel filter, cleaned Mass air flow sensor, airfilter, ran injector cleaner, cause this engine is 6 liter multi fuel injection, o2 sensor running fine, checked for intake vacum leak, none, I need help driving me nuts.
The codes you are geting are related to the mass air flow sensor you need to make sure you cleaned it well and with a cleaner specified for mass air meters brake and carb cleaner can hurt a mass air sensor. check that the air box and the hoses are secure and put on right clean the sensor agian and drive it if not you may need a new sensor did this happen after you cleaned it?
