Year of Manufacture *: 2006
this car just came in today with uneven running and engine light on I scanned it with opus in odb p0171 system too lean p0102 mass or volume air flow circuit and also misfire faults on all cylinders. and manufacture specific 2029 mixture adaption upper limit reached. 200a throttle/air mass meter incorrect ratio. this seems to me like there is an air leak in the induction system. the car is coming back next week for more tests can anybody give me pointers? any known faults in this area? thanks
