my sis has a 2003 Astra G SXi 1600 16v and yesterday all power went whilst she was on a dual carriage way in London, car came to a halt, battery seemed to then struggle to turn the car over. RAC chap ran the error codes and came up with P1550 and P1500.
I've been searching on the forum to work out what might be wrong as I'm visiting tomorrow and want to have a go at getting the car running again....it doesn't seem to be obvious so am after help please?
From what I can tell it may be one of the following but may be wrong:
- throttle pedal sensor
- throttle pedal assembly
- dirty throttle body
- throttle body
Any help disgnosing and pointing me in the right direction for repairing the car would be much appreciated, cheers.
