Having problems with your 2005 Cadillac Deville ?
My 2005 deville doesn't always start easely, and the rpm sometimes fluctuates at idle.
Todays Engines require maitainance, Filters, Polution controls, Tune Ups ect.If your Check Engine Light is not on it's not that serious.Some things to try to inprove start and idle, add a injector cleaner to a full tank of gas, it will take a while to improve but if it's dirty injectors it can help.I don't know the milage but at nearly 5 years you could need a Tune Up $ 150-250.Good Luck.
