Rough Idle on 2007 Cadillac SRX

Just purchased a certified pre owned 2007 Cadillac SRX with 47 K on it. Noted rough idle when cold, smooth when warm. Took back to dealer, who cleaned throttle body and injectors. Rough idle when cold and now rough idle intermittently when warm. Any suggestions...

Find an independent Caddy specialist to help you. Shouldn't be hard to fix, I think the dealer doesn't want to spend diagnosis time on it because that costs money.
