VXOC Astra-J/GTC

Had this problem for a while , it’s the 1.7 110 sports tourer .
Basically the revs move up and down at idle and vibrates , it’s like a weird heart beat but feels like it’s about to stall every time it drops
Anybody know why it does it , had full service couple month back but done it for ages
Many thanks

1.7cdti are common for the suction control valve to cause engine surging.

U mean fuel consumption? I don’t have the inst fuel display on mine so I won’t know what it’s using , or do u mean the fuel gauge going down more than normal thanks rusty
