At how many miles should plug wires be changed out? I have noticed my idle is a little rough. My rig has 80K. Thanks

spark plugs and most spark plug wires are made to be changed every 20000 miles. When was the last time they were changed?

if you do go to change them I suggest using some plugs and wires of good quality. Try doing a search on the topic and I'm sure you'll get some good info on both the plugs and wires.
