Hi all,

So I've been busy under the bonnet have flushed rad and engine new coolant and done engine main flush new oil and filter.

I've located and resolved my vacuum leak the two top breather hoses and reseated and cleaned throttle body.

The plugs,cool pack,coolant sensor and map sensor I've also changed.

However I'm still getting trim bank 1 running rich on the obd scanner this is  affecting the mpg should I now be looking towards my pre cat lambda sensor ???

Yes.

Thank you 

Do you happen to know the socket size for the sensor please ???

22, I think.

Cool that's what I thought as I wanted to get a slotted socket as may do the rest sensor also
