Idling problem MYOO Uk Turbo

Can anyone help diagnose this problem, I thought a service would solve it but apparently not.

Scenario: Once the car warms up at idle the engine loses revs and feels as though it will cut out (which it will sometimes if you don't blip the throttle)

I had the spark plugs changed recently when serviced and I'm unsure as what would be causing it.

Any help would be appreciated thanks...

I'd go with this one. Let the engine warm up, when warm unplug the MAF..if it doesn't stall then the MAF is knackered....

I didn't put the plugs in so can't be certain if they were gapped properly, hopefully they were. I'll check the maf sensor as mentioned above, I don't think it would be the BOV but we'll see eh!

If it is the MAF can I just swap it over with a new one, or does it need to be done by a garage with diagnostics?

Thanks

Very easy to do by yourself, all you need is one of those security screw driver heads to undo the 2 screws. Unplug the connector, swap, plug back in.

It would also be advisable doing an ECU reset at this point to clean everything up...

PS MAF is about £77.

To the OP: no one has mentioned it yet, but keep the car OFF boost till the issue is resolved, if it is the MAF and you drive the car on boost, you risk damaging your engine!
