Sudden loss of throttle response

Good stuff!

When replacing a MAF, only ever use a proper one: Bosch, Siemens or febi which is a real one with the logos ground off. Ebay ones are crap and even 'good' names like Bremi are useless.

Agree with @Andyboy, always use oem replacement sensors, in particular the Maf, been down the road of trying cheap Maf off ebay, it didn't work at all. Fitted oem one and that solved my running issue straight away. Camshaft sensors always best to go oem parts, I have used Hass brand and they work ok and are cheaper than the usual brands that were oem.
