Let's start over......
how many miles on those plugs now?
Probably around 80,000 miles, I know, I know. Just now started noticing the sporadic rough idle. They're the second set since I had them changed under a tsb under original warranty.
60k is the recommended mileage interval to change them at...so ya it could definitely be the plugs too....
I do all three every 15k-20k.....better mileage and better response.....
