1. Get the Bentley manual and test the coolent-related senders/sensors.
2. Change the thermostat if it's over 2 years old.
3. Check the fuel pump relay. it may be affected when it gets hot under the
hood.
4. Get back to the group with your findings.

Alright all ye who are strong in BMW-fu

98.4 percent of the time this car runs absolutely fantastic. The other
times it acts as though it is overheating then stumbles and runs quite
poorly. The temp needle climbs, it stumbles, won't accelerate, then a
few minutes later it clears up and again...runs great. I have replaced
the thermostat. I have, but have not yet replaced, the coolant temp
sensor. I have replaced the airflow meter, on the advice of a
mechanic. Fortunately, it was cheap...(EBAY) but it made no
difference. I love the car...It's in great shape...but HELP!
