Tecnobuffs- Name That Problem!...

![Question](https://www.scoobynet.com/images/icons/icon5.gif)
My MY99 UK turbo Impreza has just failed the MOT on excessive emissions. Before i took it in it was doing the following on tickover- alternating between 850rpm and 500rpm at 2 second intervals, i.e a regularly lumpy tickover.
A friend has suggested it may be air flow meter or lamda sensor or cat gone **** up. So come on people- name that fault...
No prizes for the winner... :-)

When my Lambda sensor failed the revs would drop & rise when pulling up to junctions. Car ran really rich which wouldn't help emissions.
I thought a dodgy MAF would cause the car to run lean under load, not rich under closed-loop conditions ???
