I'm at 106K on my 03 Lancer, think it's about time for the tune-up. From what I've heard, I'd probably get the best deal (I know this goes against all common sense) form the dealer for this job. I recently did the plugs and wires, so not doing that should take down some of the cost, right? Other than that, anyone know what I should expect to spend on it?

Also, could anyone elaborate on what is typically done during said 100K tune-up? Timing-belt, fluids, etc...

Thanks

I just pulled out my owner's manual and here is what it says: replace air filter, replace sparks plugs (which you already did) change oil of course and filter, check automatic transmission fluid level and condition, inspect brake pads and rotors, inspect rear brake lines and rear wheel cylinders, check brake hoses for wear, inspect drive shaft boots for grease leaks and damage (not sure if you have to worry about that, and check your suspension, and last rotate your tires. Hope this helps out.

also. timing belt.... and serpintine belts. regrease your fittings.
if u lose your timing your pistons will run into the valves and screw up everything....
