2003 Cadillac cts service idle control reduce engine power


I have 03 cts and service idol control shows when I start the car sometimes and sometimes comes on while driving. I had everything cleaned and everything was good for a week then the engine light would go on and off, I think I may need a new sensor for the idol control or replace it. My question is if I keep driving it will it effect anything else ?
