Fuel system too lean (Bank 1)
Basically the ECU is detecting the engine is running too lean, so it compensates by injecting more fuel. This lean condition could be caused by low fuel pressure/faulty fuel system, a leak in the intake system, or a bad oxygen sensor.
- Check fuel system pressure. It should read around 38 PSI with vacuum hose connected, 46 PSI disconnected.
- Check for leaks in the intake system. A leak allows unmetered air to enter the system, causing a lean condition.
- Check the mass air flow sensor (MAFS)
- Check the throttle position sensor (TPS)
- Check the oxygen sensor
