hey, currently have a 1985 318i with a faulty (actually, wrong meter all together...) airflow meter.
it is my understanding that this meter is whats causing my bmw to have trouble starting, firing on all cyl, and also whats flooding the engine constantly.
i have sufficient spark at the plugs and the injectors are just pouring fuel into the chambers. what im assuming is, the airflow sensor is giving an improper reading. probably because its the wrong one. (currently have part #0280202082 and i need part #0280202039)
so. what im looking for is a good deal on an airflow meter with the part # 0280202039. if theres anyone out there who has one for sale or mayhaps even a late christmas present (haha!), let me know!
in fact, i may even be wrong about what meter i actually need. im just going with how the prongs on the harness look. (#0280202039 has 5 prongs, and #0280202082 has only 4.) the chilton's manual shows the meter to have 5.
However, If your problem is hard start and flooding, it suggest you train your sights on the Thermo Time Switch and the ECT Sensor. These 2 sensors control how much of gas the injectors should be putting out depending on engine temps.

Try autohausaz.com theyre out of arizona but soooooooooo much cheaper than anybody around here. Theyve saved me thousands on my '90 735il and they have a mass airflow meter for mine so they prob will have one for yours.
