The next things I’m going to check are fuel pressure reg and coil pack as when I replaced the old o2 sensor it was as black as the ace of spades
In the last 1500kms it has had brand new fuel pump ,fuel filter, leads and plugs.
Thankyou

The inlet manifold gasket is a very common problem with these cars and the issues that you are experiencing point to this may be the problem.
The second most common issue is the coil pack.
