08 Mazda 3 Takara 1.6 petrol, I have had this issue since I bought the car one year ago, it hasn't gotten worse, instead it has gotten slightly better after I cleaned the MAF sensor, the weird idle drop doesn't occur at all with MAF sensor unplugged. 3 garages i went to pointed out at 3 different things, lambda sensor, injectors and intake manifold gasket. No codes in the video because I reset the ECU. However before it had thrown P2177 and P2187, scanned at a local garage.

Tools arrived today, cleaned throttle body and put in premium fuel and injector cleaner, the issue still persists.. will see if the injector cleaner does its job over the next days.
