I have an Astra-G (MY98) with a strange fault! When travelling up a slight
gradient at 72 mph, the engine management light illuminates with trouble
code P1125 - critical system malfunction-1, set present. I have checked and
substituted all vacuum related items including the air mass meter and
pressure sensor. The vehicle otherwise performs normally with no other
symtoms.
Any thoughts on what could be causing the fault would be appreciated.
