Replace the thermostat in the air filter box so the engine can breathe cool air as it's supposed to. If that's stuck over to the "warm" side, it could be frying the AMM too. It may already be dying from what you describe. Some cars will run ok with it off or disconnected, but that often means it's bad or going bad. I was able to get a good used one for a friend's 1990 245 this summer for $75. The unit you have is the "016" part (last 3 digits of the part number). If you decide to get one, avoid rebuilts. New Bosch, or good used only.

You're on the right track, though you might need more work on vacuum leaks, such as an intake manifold gasket, and/or fuel injector seals.

Good luck!
