i have a problem with my v6, it's running much too lean. Maf and lambda both been replaced, previous lambda was'nt switching and the end was very white when it was removed, no trace of carbon at all. Power seems to be dropping gradually and fuel economy is getting worse. I know the v6 and mpg dont always go together but iv'e gone from getting 28-32 to the gallon, down to 24mpg whether i drive like miss daisy or the stig. Spoken to augusto at Red Dot and Steve at southern carbs in SW london and both strongly recommend getting the injectors asnu (ultrasonically) cleaned. Has anyone had this done? also was there a noticable difference. Any help much appreciated.
