My '93 325i will not pass emissions. The CEL light is showing and the code I get is 1215 Mass Air Flow Sensor. After reading several posts here and other forums a followed some suggestions and decided to attempt to clean it. I have also taken the car to the dealership for a diagnostic just to verify that only the MAF needs to be replaced.

Diagnostic returned that I need to replace the MAF and the O2 sensor, and I need a throttle adjustment.

Well I have replaced the O2 sensor and am awaiting the delivery of a new MAF. Can someone advise how I can do a throttle adjustment?
