Problems with air mass meter Alfa 156
I've had two Alfa 156 where, with both of them, there's been a problem with the air mass meter. The first one stopped working in an original 1,8 engine. Later I replaced the engine with a 2,5l v6. The new air mass meter also stopped working. I now have a new original 2,5l V6, and I've already "used up" two air mass meters - in one weekend! Both cars has been rebuilt into rallycross cars, but several of the air mass meters stopped working before I even could test the car. The only change done to the air intake is changing the original air filter to a sports filter. I really have no idea what to do to get the air mass meters to work. I have to unplug it and drive the race without, losing a lot of acceleration and horsepower.
I also drive a V6 as my everyday car, it has the original air filter, and the air mass meter still works. Does anyone have any idea why this might happen?
