Can’t find MAP or MAF sensors

[Onions]

I had diagnostics done on my car a few days ago because of a misfire the diagnostics told me it was caused by a faulty mass sensor I have looked in all the usual places i.e. on top the airbox but I cannot find it anywhere also I thought maybe it would be a map sensor but again I cannot find this anywhere it is not in all the usual places I have been told to look any help would be appreciated thanks
