My 1995 850 Turbo has an issue with idling in warm weather. It always starts easily and runs good from cold. When the weather is hot it will only idle for a couple of minutes before it drops to 500 RPM or less. The temp guage shows normal engine temp but the car does not do this in cooler temperatures. After the idle drops it will not rev and is very sluggish when trying to get going. Once I get it moving, it clears itself out and runs fine. It acts like it is choking itself out and once there is sufficent air flow it runs fine. I have had two instances where it flooded out and refused to start, so I had to pull the plugs, disable the injectors and crank it for a bit. After doing this, it started up and ran fine again. Could this be a Mass Airflow Sensor issue?
