Ok i got this problem with me CO% (i am sure everyone know by now )

Thanks to Stu and Gareth i've come a long way and closer to the problem cheers guys

So i reckon its time to renew the lamdba sensor and see what happens

But are there any other ones (other then from Fords) that can be used for the proper reading as you all well know Fords like your money!

Cheers
