I have a 1994 BMW 318IS with 120,000 miles. The check engine light came on and I had it read. It said I had a bad Mass Air Flow Sensor. I bought one from Auto Zone and it will be here tomorrow. I was looking for some information on how the best way to go about replacing it and where I might find a repair manual.

Thanks
JR

JR, My suggestion is to purchase a Bentley manual from amazon.com for your car.As to the air flow meter, it is very straightforward. remove the clamps holding the air boot on and the bolts holding the air box, replace the air flow meter and reinstall. repost if you need more help
