Check engine light on. When car starts idle revs up for a min. Then goes down. Then continues this process as long as the car is on. Up and down. Seems like its going to cut off but doesn't. Does it while driving also.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on
