Astra running very rough - Snapdragon
Hi All

I have been experiencing problems with my Astra for 2 months (on and off) I had noticed that the revs were dropping when I pressed on the accelerator and would stall if I lifted off to quickly!

It has been in for a 60k service and all filters changed, I thought the fuel filter might have been clogged up, but the problem still exists

May be just coincidence but I have noticed an airlock in the coolant since the problem started.

What age & engine size is the Astra?
Also petrol or diesel?
