Hi all,

My Ford Mondeo MK3 is giving me a headache.The gearbox and engine lights are on.I ran diagnostics on the ECU which returned trouble codes:P0171,P0403,P1131,P0073,P1000,P1432.

It seems the car has problems with the Engine Thermostat,,Heated O2 Sensor and ERG Sensor.I don't know where to start.The car drives and it seems when the fuel pump get hot the car starts jerking and refusing to change gears.

I would like more advise on what to look out for before I replace these sensors.

Many thanks for your advise.
