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.
