I have a 97 z3 roadster 1.9.... My initial problem started with hesitation during acceleration. Check engine light came on and said it was the mass air flow sensor. I changed it and fixxed that problem. My problem now is after it heats up approximatly a couple of minutes running it trys to die... The rmp's drop. It doesnt actually die. I have changed the idle control valve and it did not fix it. I have already replaced the plugs and wires. I am ready to run this car off a cliff...... Seriously. The bmw dealership cant give me any anwsers eithier. Please help.....
