Should I claen intake valves?

I have a Jetta 2019 with 80k miles, it was having misfires (flashing check engine light, rumbling, etc). Dealer did a software update and will replace the fuel Injector under warranty. They also recommended "decarbonization of Intake valves". They said that the intake manifold will be removed so the labor will overlap. They said I could get it done for $550 but originally it's a $1400 job.

Should I just do It?
