As topbloke says the airflow/mass meter rarely gives a code but more likely the wayward signals from the sensor cause the O2 sensor to go ape trying to cope and the ecu flags this as a fault.

so how can the garage say that its a lamda fault and make you pay for their guess, get it back to them and ask them to get it code read properly and stop guessing, if they cant/wont get it read then tell them that you will get it done and will send them the bill for the code read/lamda, sorry but it just aint good enough,nowadays garages can barely exsist without a code reader/ something to put service lights out

Well obviously we aren't happy it's been wrongly diagnosed....it's one of those problems though that only crops up under extreme circumstances.
All too often this does happen....the garage think they have fixed it, but the problem re-occurs.
Is it a serious problem?...ie, can it be expensive in the long run if it isn't solved?
How should the garage be approached?....ie "Hi, brought this in a couple of weeks ago, and you charged me (I think) £127 to fix the problem, but you've not fixed it"
Unrelated I think...but thought I would mention it....
I changed the spark plugs a few weeks back and one of them didn't have either of the electrodes on it, just the centre one, and some of the insulation around it was broken. It wasn't mis-firing at all, which really surprised me. Put new plugs in and the car didn't seem any different. What could have cause that?

Well the car goes back to the garage tomorrow.....and my own car (Rover 25) has its MOT tomorrow also
