Intermittent-pulsating power delivery ?

That said .......
What if I have a boost leak somewhere, and plugging the MAF in detects this therefore making the car hunt around ?
Do these even fail much on the TSFI ? these parts aren't exactly cheap :(

In the end decided to get a used MAF, managed to get one for £30 from someone breaking a car. Decided to remove the airbox to clean/re-oil the pipervcross air filter and also noticed the plastic funnel rattling around inside (the silly plastic clips have snapped off).
Binned that, as it serves no viable purpose...Anyway refitted and same with MAF, reset the codes with chepo tool, started car with no issue.
Booted it around for a bit after warm up and seems to drive fine (but ill drive it a bit more as remember the prior issue was intermittent).
Checked for more codes again and the other mish mash codes have disappeared as per the air mass sending dodgy reading to various other parts of the car...... apart from the lamber sensor 0537-033 which keeps comming back. Why has this started showing up now ?
Car still drives fine and now I guess I might have to fork out for one of these now, £70 for a bosch part.
