Hey Everyone,
I hope I am posting this in the right place. I just bought a 2004 Yukon Denali with 166,000 miles on it. I have a second child on the way and needed more room. Since there is no warranty, my loving wife is willing to let me try to do the maintenance. No oil leaks and the service is up to date. I know I need to replace the air filter but I was wondering what else might need changing. I am a beginner at automotive care. I can change the oil and brake pads but that is as far as I have gone. Any advice would be great. Thanks

If it were me I'd replace the spark plugs, plug wires, perform injector cleaning, and replace all fluids(coolant, transmission/filter, differential). And maybe the oxygen sensors as well.
