Why does the idle drop like it's about to stall after coming to a stop. Then a high pitch noise comes from the engine area, which then, when accelerating, the car only goes about 4 mph. Checked the DTC'S. Code 157-MAF sensor.542-fuel pump continuously running (PCM to pump). There's also a noticeable fuel order during driving and idle.
