just the usual...check: air pressure in tires, air filter, tranny fluid, brake fluid, serpentine belt, and coolant and hoses. change motor oil(synthetic) to a 0W30 viscosity w/ filter of course. put in a quality fuel system cleaner or make your own. clean the throttle body.
According to Vibe forums and the manual. 100,000 miles when it's suggested to do a tune-up. But most of the Vibe forums talk about tune-ups to increase performance. I dont care about that. I want, of course, better mpg, but also parts and stuff that will help keep this car going strong way beyond 200,000 miles. I know it needs a new belt, a rad. flush. The brake fluid is just a hair below full. Do you think a brake flush would be good?
"But Doc, we dont' have enough road to get it up to 88 miles per hour"
If your car is at 100,000 miles then:
1) New Spark plugs
2) New Spark plug wires or coil on plugs
3) New radiator hoses
4) new timing belt (if not done yet)
5) brake fluid flush
6) Change out power steering fluid (use giant syringe and take out as much as you can and replace)
7) New serpentine belt or drive belts (if never replaced)
8) New fuel filter
9) Check brake pads/rotors
