Lambda Control 2 |
This code is stored when the DME detects excessive deviations in the air-fuel mixture (too rich or too lean) for longer than 10 seconds. Possible causes: Fuel tank ran empty, Incorrect Fuel Pressure, Injector valve defective or coked, Engine Temperature Sensor defective, Secondary air leak, Fuel evaporation control system defective, Air Flow Meter defective and/or the combustion is being disturbed by mechanical failure (Spark plugs, compression, intake/exhaust valves, ...etc.)
So what was that loud sound your heard? Did happen to figure out what it was?
No idea what made the sound. It only lasted a moment.
I sprayed starter fluid into the throttle body and it started right up so I'll be checking: fuel pump fuse, fuel pump relay, fuel filter, fuel pump
At this point I'm betting it is the fuel filter but I'm going to need a way to get the car in the air so I can take a look and know what to order. Since I'm new in town and don't know many people... this may prove to be difficult.
On another note: There is something on the engine on the driver's side next to the firewall that hums when I turn the key on. When I touch the top of it, it is hot and almost burns my finger. Don't know what it is but it looks like it is connected to a line that goes down under the motor.
