Hi, My 76 280z has a serious over fueling problem. I can only get the engine to start and idle when the Air Flow Meter is disconnected. It will run for a few seconds, however it will run very rich. The engine will then flood and stall. After a bit of research its seems that there could be a few problems. One being the cold start Thermotime switch. However the problem still occurs when the cold start injector is unplugged. The other possible causes could be: Throttle Valve switch, (possible idle problem) Air Regulator (however from research this helps with cold starts, and is not prone to being stuck open as it usually gets stuck closed) Faulty Air Flow Meter (from research these do not tend to go wrong often) I have the Fuel Injection manual so will being going through this over the next week. But if anyone can help with additional information, or let me know if im on the wrong/right track. Thanks
