Hi I have really high emissions on my 1999 4.0 V8 discovery2, It had a fault code for bank 1 probe 1 lambda sensor so i've changed it and cleared the faults but still got high emissions, CO2, HC, Lambda are all out of limits. are there any common problem areas that I should be looking at apart from the cats :doh:

Thanks steve.

Yep took it for a hard 7+ mile drive and straight in on the gas tester.

I presume it is motronic system, worth trying new crank sensor or/and air flow, crank sensors dont allways record faults.

Fixed the code reader must of been telling me the wrong side fitted the lambda sensor in the other side and it went straight through and only after a 5 min warm up.
