Hello!
I have a Corolla with a Dual VVT-I 2ZR-FE 1.8 gasoline engine (Naphtha), and I have problems with the RPM, what happens is that when the gear is in position "D" and the vehicle is completely braked by the RPM tachometer becomes unstable (starts to rise and fall). I already changed the 4 spark plugs and cleaned the MAF sensor.
I leave here a photo of the spark plugs and a GIF of the RPM tach when I am braking in "D".
Can someone help me to solve this problem?
