Hello All,
I have two '96 850 wagons (non-turbos/5 speed manuals) and a '99 XC. I do complete tune-ups on these cars every 30,000 miles. I change the spark plug wires at 60,000 intervals. I think on one occasion, before I hit 60K on one of the cars, a wire shorted, and caused a misfire and in turn the CEL came on.
My question is: should I replace the spark plug wires ever 30K or 60K?
Incidently, the Volvo owner's manual doesn't suggest a time/mileage limit to change the wires, but instead to check them for wear.
I look forward to hearing your opinions.
Thanks!
Hugh
