Hi Nick,

Not a lot to go on here and I fear that you are opening yourself up to a bit of criticism from other techs. However, will try to help. Was the test at fast or natural idle? Can you scan/scope Lambda Sensor? Would like to see gas figures for both natural and fast idle. My initial hunch on the limited info provided would be Lambda sensor with possible Cat damage.

Regards

Pete M

Hi, the co and HC give impression of rich mix, does it misfire? Fuel pressure, is it 2.5 bar or higher? Blocked air filter? Leaking ibnjector? Does CO drop dramatically if you diconnect any of the injectors? You could also do a power balance test, keep reves high and disconnect each injector and see which one makes most or least difference.

Too much fuel not enough air but as mentioned few more test results needed to offer help.
