My cat was clogged. I brought a bottle of cat cleaner from Halfords. Put it in when you have quarter tank of petrol. Drive hard and it burns the crap away. Also use premium petrol.

All that seems to be clear. Now an nit coming back up on diagnostic. But crank shaft position sensor a coming up. Took it off seems to come on when start up first or cools down was temp up to half half engine light stays off if I remove off when temp ok any ideas. I’m sure I had this sensor put on last year.
