Looks like its the ADZ engine as its a 96 P reg.
When it was in the garage a few weeks back for the brakes to be done I asked him to give it the once over because it is noisy and a little short on power so I thought exhaust. He said the exhaust was fine but the cat was the problem, he said it was fine but would need replacing sooner rather than later.
I initially thought it meant hundreds as thats what I have paid previously on Vauxhalls :embarassed: but it appears not.
Would the Cat make a big difference in power if it was shot?
