1998 BMW 750iL 5.4L Poor Idle Quality, Hesitation, Poor Fuel Economy
after a complete tune-up due to all cylinder misfire the service engine is now off but the short term fuel trim is at +20.5 and you can here a large vacuum leak in the back/rear driver side of the engine/intake area. is there a common leak? Hoses? Intake?
