I am sure the answer probably lies somewhere but I was wondring if I have to change the wires when I change the spark plugs in my SC 400? Specially if they appear to be ok. I am taking the car to the shop tomorrow so would appreciate any comments...

 

How old are the wires? If you don't know just do them, can't hurt.

 

you dont have to, but a true tune-up would include replacing them.

 

Thanks..as it turms out when they openned the cover they saw some cracks on the timing belt and suggested that I change it. Not sure when it was changed last time. So am getting the whole thing done, timing belt, water pump, plugs wires rotars....gonna cost me close to 1500 Canadian $$!! i probably could have let the belt break but I just did not feel I want to take any chances..
