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.
