What do you change on the engine when you do a tune up? I'm thinking plugs, wires, and what else?

 

I also put in new gear oil in the differental,and usually do a oil change when I do the plugs and wires.Check the O2 sensors visually.I also use that fuel injector cleaner that you spray into the intake clean out the builup of carbon.Then again I am quite the maintance freak What ever the normal time to service the car cut that in half thats me.

 

Is that cleaner stuff you use called seafoam?

 

Heres my idea of a tune-up....

new spark plugs
spark plug wires
coil & wire
fuel filter
fuel injector cleaner
flush coolant
change oil
change differential fluid

 

change the filter in the tranny or flush it and the filter
