I'll second this suggestion.  I would say that if original plug wires are
on a ten year car they should be replaced with OEM Bosch just as a routine
service item...don't waste time checking them to see whether they test
good/bad, etc.  I have seen night/day improvement from new plug wires even
when the old ones tested OK.  In one case the improvement included a 5 mpg
increase in gas mileage... on my 87 5ks.  So cost of new wires shouldn't be
an obstacle, esp considering they can be had for $50.
