Well, the crank sensor needs to be replaced ASAP or it will leave you standing so do that anyway.
Any air leak into the induction system will cause errors in the fuelling so repair / replace the ICV hose.
Are there any leaks anywhere in the exhaust system? Manifold gaskets? Pinholes? Joints blowing slightly?
Just because it's failed on the Lambda reading it doesn't mean faulty Lambda sensors.
Is the engine running at the correct temperature (mid-gauge)? Does it come up to temperature quickly (within 1st 2 or 3 miles from a cold start)?

I have a replacement pipe for the ICV so will replace that at the weekend.
Temp is spot on.
Didn't notice any holes or blows when under it sorting the brake pipes but one joint after the cat is caked in Paste! so there may be a blow somewhere.It is a bit throaty but aren't they all

Guy testing it acknowledged the Lambda level was coming down and at the same stroke mentioned he had been rammed with MOT's so suspect the car was cold when he carried out the Emissions test which never helps does it

, cheers for the replies and will keep you posted.
