Im coming up on 100,000 miles and it is time for a tune up, after changing coils and plugs what else should i be looking for?

 

Consider changing brake fluid and power steering fluid.

Do change coolant and transmission fluid.

Check the belts (like I ever do that myself, but I know i'm supposed to), check the PCV valve, check CV boots...

 

replace the fuel filter
check the strut boots
clean throttle body
check the brake pads and rotors
change/clean the air filter
