97 Deville Idle and Coolant
For the last year I have had problems with my coolant, always having to put it in. Almost a year ago I had a new radiator put in and that seemed to of solved the issue, recently my light to "check coolant level" has popped up. My other issue within the last week is my service engine soon light has came on and off and my car has been idling rough when I come to a light and whatnot. Today the SES light was flashing on and off and car is still idling. PLEASE help me if you have any advice.
