Ive got an astra mk4 with Z14XE in it. management light is on, codes for both o2 sensors and code for purge valve. changed all 3 and no difference. changed the ECU and no difference.
Aswell as that sometimes when i put the clutch down the car revs up like mad then drops back to normal, seems to only do this when it feels like it. ive changed throttle body and egr valve and no difference again.
Anyone any ideas on what i can try and do to fix it??? startin to get F****d off with it now!
