Thanks for that!

I havent checked the ecu for error codes for a while so that will be first thing before i even start messing.

Still spending far to long checking ABS error codes and trying to rectify that on a shoe string.

No I was just sat in my chair thinking, and had remembered reading a few posts were people had mentioned that part as a suspect for poor or under performing running.

Car when it has been on the road and it hasn't for a while, some times runs like a dream/scalded cat and other times you take her out and she seems to hesitate in boosting/running well.

Other times she will be pulling away and boosting and the car seems to back off mid boost.

Thing is tho, I wonder if it could be something as simple as its not happy with the fuel?
I have filled the car up last two times from a garage that only sells regular petrol.

Next tank I am going to put shell one with the higher octane.

Also want to check wiring for the Lamda sensor is right, as it had snapped off and I am unsure if its been reconnected to right wiring?
