1998 BMW 528i 2.8L Poor Idle Quality, Misfire, MIL Lamp on, noise from intake
Interesting problem ( I hate interesting). This car has very poor idle performance. Sets multiple codes as specified above. What is baffling to me is that there is a very hard mechanical nosie from area of intake plenum. Sounds almost like a flap slamming shut...
