:)The sympoms you are getting and the oxygen sensor fault codes suggest to me that you have an air leak.

Just to update you

replaced both lambda sensors at garage, still poor idle,

they said need new throttle body.

To which I said can’t it be cleaned, as I read on a forum it’s a common fault and a clean usually fixes it.

But the mechanic continues to say he will price up a new throttle body and let me know how much and see if I wanted them to get it and fit it.

To my surprise the next day when I got the call, they told me car was ready and all that was needed was to clean the throttle body.

I got the feeling they didn’t know they could clean it.

So thanks to this forum I was able to suggest to them about cleaning the throttle body and save me about £300.

thank you all

The car is now running better than when I first got it
