Vauxhall Meriva temporary loss of power/acceleration

Could try changing fuel filter . Another possible cause could be the TPS ( Throttle Position Sensor ) but USUALLY throws a code

Can I ask if you managed to get this sorted and if so what it was? I also have an auto meriva and having the exact same problem. I've been told its a common fault from water getting into the fuse box. Having it looked at tomorrow.

I too have the same problem, my car is currently in the garage, they’ve just called to say it’s showing nothing on the diagnostic but it’s dreadful to drive, twice now I’ve been driving and as I’ve excelerated the car has died, loss of all power including steering, I’m lucky I’ve not been hit by another car as I was on a fly over at the time. There going to try changing the filters, but if that fails it needs a Vauxhall dealer to look at it, I know that I’ll be scared to drive it when I get it back. The odd thing is, when it lost all power it started straight away.
