Default Tune up question

2001 Bonneville SE.111,000 miles. I have decided to keep this car and drive it until it won't go. I have started getting it ready for the long haul be replacing the upper and lower radiator hoses, sepentine belt, tires, brakes, reflushed the coolant, and serviced the tranny, The car runs great, and is good on gas. My question is ,should I replace the plugs and wires, clean the injectors, replace the PCV valve and fuel filter as a precautioanry measure, or just keep drivng until it starts to run bad. I don't want to spend money I don't have to. Would these things I haven't done be worth$ 300-$400 to get done now? Opinions???????? Anything I have overlooked??

Thanks for your much appreciated advice.
Bill

I wouldnt worry about the injectors but if the other stuff is original definitely change them if you plan on keeping it.

You only need to replace the wires if you develop an issue.
The plugs you may want to change now if you dont know how many miles on them.
The fuel injectors should still be fine but run some injector cleaner in your tank once in while.
You may want to do a seafoam treatment to your top end, it keeps the internals clean and removes built up carbon that helps with fuel mileage.

By the way, the plugs and wires are all original equipment, as well as everything else I haven't replaced in the original post.111,000 miles.

Personally I would change wires and plugs and fuel filter if you can afford it, if not wait till you can.That way you are fresh for another 111000 miles.

seafoam is a product you can buy at any auto store. you can put it in your gas tank to clean the fuel system (including injectors)

you can also put some in through the vaccum line to clean more engine internals
