Air mass sensor location on 1993 volvo 940?

Since I see you already did all of the normal tuneup type stuff, I would also like to point out the air mass meter:

The way this thing works is there is a heating element inside of it:

The engine knows how much air is entering the engine, by how fast that heating element cools off. If that element is dirty, it will not cool off as fast. So the computer will think no air is entering the engine, and will dose the fuel accordingly. Once it gets going..smooth again, it runs a bit more like normal.

You will want to use something like brake cleaner for this, and make SURE that the sensor is completely dry before you hook it up, to see if it works... Which it should.
