the exact same thing happened to me today.
yesterday before there was the engine malfunction that happened today, I heard that the sound of the engine on rev matching (or just free revving) was different, I took it to the dealer but since the computer didn't tell them anything, they didn't know what to do.
today after the malfunction I took it to them again and they told me it was the throttle valve actuator
what does the actuator do and would it make a different engine sound if it goes bad?
