Recently went in for a major service, had o2 sensors, throttle body cleaned out and whole fuel system checked for leaks but i'm still managing only 350 kms out of a full normal Exec tank. That's driving like a granny on a straight stretch of road! Boojakz
have you tried the engine temp sensor???? that can also screw wit the computer and give a faulty reading. thats the problem i had with my VS now she runs like a dream
