P1124 HYUNDAI - Long Term Fuel Trim Error System Lean... Possible causes... - Low fuel pressure - Fuel filter plugged - Fualty fuel pump - Engine mechanical condition - Large vacuum leak..... So check vacuum lines for cracks, snug up the intake manifold, make sure the throttle body gasket is good. Just check anywhere there is a main source of vacuum.
