Just out of curiousity... How do you know this?
Well...I thought my car been intermittently misfiring around 6000rpm. I felt it hiccup at the trackday but I eventually forgot about it. So I took it to my Ford guy who runs a tuning company out of a local dealership. We put it on the dyno to make sure I wasn't imagining things.
Sure enough at ~6000rpm the hp line took a wild dip for about 400rpm. The graph itself was very jumpy and not smooth. Aric immediately said it was the plug wires. He said that the FRPP wires are hit and miss with the Contours and Focuses he's put them on. So I took his advice and I'm putting the OEM ones on.
