When to do tune up.
My '04 coupe just turned past 50K miles. Outside of regularly schedule oil and air filter changes and chassis lubes. There's never been any engine work and it's still performing well. I am noticing that the engine sometimes hesitates to fire up on the first key turn. Is it time for a tune up, and if so, what needs to be checked?
I would change the spark plugs first.GM says the factory plugs can last 100k! right!I pulled mine at 50k and they looked fine but worn down.Guess what poor performance,bad gas mileage.Buy a new set.Next check the air filter,if it's dirty,replace it.These car are no different as far as tune-ups go,most people can do them theirselfs.The fuel filter change is harder.Do these things along with your oil and filter changes and you should be good to go!
It's got so it seems to me that the Internet has created a lot more Horses A$$'s than we have Horses!

I have a little hesitation when I step on the gas, you think this is a possibility? What size hose is it? Is it more like a fuel hose or vacuum hose? The car is up on the lift, so I can't just pop the hood to take a look, but I will check it as soon as I get it on the ground.
the short rubber nipple on the throttle body for the PCV valve 3 times in 7 years, if it's leaking it can cause your symptoms and others depending the size of the vacuum leak!

to Toms01-the hose jnnkie is talking about is the small rubber hose on the pvc valve to the throttle body.If you stand in front of your vette it will be on the left side throttle body.Its a short piece of hose and very thin rubber!Mime had a big hole in it ,I don't know why.It threw a check engine lite every now and then.I'd clear it and in a couple of days it came back!I cut a piece of fuel line hose,thicker,and replaced it,job done!GM parts probly want a million bucks for the factory replacement! goodluck,check yours out
