Stupid question but looking at Lambda sensors, are there two? Looking at parts there is a ‘before’ and ‘after’ catalytic.
Looking at symptoms it does sound exactly like the lambda sensor however Lambda and MAF have similar symptoms so will fit the MAF and give it a go.

I’ve bought an Audi A4 b8 (2010) with 92k miles and today I took it for a drive up the motorway. I noticed that whilst driving the rev needle is bouncing and the car feels ‘odd’. It still accelerates well but it feels a bit jerky occasionally.
Then when coming to a stop it’s quite a jerky slowing down and acceleration from stop.
The idle has always been a bit lumpy but today in todays heat (no AC on) it was a bit more of an uncomfortable drive due to the jerky start and stop and what feels like jerky gear changes.
I’ve already changed the ignition coils, spark plugs, air filters etc. I’ve ordered a MAF sensor which will hopefully be here in a couple of days.
any ideas on what could be causing this.

I’m booked in for a cambelt and full service but if I can save a bit of money and do this myself then I’m going to try lol
thanks for the advice though.
