  • Why is my '98 Ford windstar is running rough after a tune up? I changed out the plugs and wires and it ran good for a day or two but has a lot of hesitation at lower rpms but if I speed up it goes away. Also have a gas smell in my air conditioning when I'm stopped but not while driving. Can anyone help? I'm tired of putting money in this thing.

I own a 2005 Ford Mustang GT and I never got any service records from the car lot it was bought from or any service records from previous owners so now I'm looking at possibly having to do a tune up on my car and I need to know what a tune up for my car consists of. I want to know what is changed and done in a tune up. I already changed the oil in it and all that's left is the tune up. Serious answers only please. Provide links if possible.
