just installed a used COP setup. went in great, look great and runs awesome except at cruising speeds, slight accel and slight decel, it starts to misfire. its really starting to piss me off especially when 45 out of 50 miles daily is on the interstate. any help is greatly appreciated.
i know all the coils and wiring is good because it idles perfect and does great under acceleration, its just when you start to level out it starts misfiring.
