I occasionally have an issue on my Sedona with rough idle - I run a can of seafoam through it and it clears up.
I don't believe I've had rough idle on my Cadenza, though I occasionally run a tank of premium fuel through it, so that might be doing the same thing as the seafoam.
Since you've already installed new injectors, it must be a different issue than what seafoam would fix.
