2005 Vauxhall Corsa Two Wheel Drive Manual 47500 miles
When starting the car the headlights & front indicators come on straight away even though the switch is off, at this point the car will start and sit ticking over BUT when you turn the lights on with the switch it wants to cut out, there is no power on the accelerator to rev it when the lights are on. There is no warning or engine management lights come on at all.
I have had a diagnostic done and no fault are coming back. This has totally baffled me and im now needing help please.
