An engine has a rough idle condition with high HC (Hydrocarbon) emissions only at idle and low speeds.  A diagnostic trouble code (DTC) indicating a lean air-fuel ratio is stored in the powertrain control module (PCM) memory. Emissions of CO and NOX meet emission standards.  At 2,500 engine rpm, the HC emissions are normal. The MOST likely cause of this problem is which of these:
◦ Defective ECT (engine coolant temperature) sensor
◦ Low fuel-pump pressure
◦ Defective injectors
◦ Stuck open EGR valve
