Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
I have a astra sri 1.8 petrol and it's 2005,
Has 135k on the clock,
Full service history,
Cam belt changed and water pump 25k ago,
Any mechanics or anyone know or had this problem before? in the morning I get bouncing revs and a knocking sound, only for a couple of minutes then...
