Yeah, that made me a little nervous as well. I watched a youtube video of a guy diagnosing one on a Mirage. He was speaking Spanish so I didn't understand a lot of what he was saying but I heard him mention 5K rpm's more than once. The troubleshooting procedure Top Fuel posted mentioned 3500 rpm's minimum for running the testing procedure. I was trying to keep it somewhere in between 3500 and 5000 rpm's. I don't know about the CVT's, mine's a manual. At interstate speeds 70-75 I'm turning over 4K and average around 35-40 mpg. But if I stay around town averaging 50-55 mph turning 2500-3000 rpm the fuel mileage greatly improves to 45-50 mpg. I wish they would've made 5th gear a little taller for the interstate.I just watched part of your video and yikes, go easy on the rev-offs unless you you are trying to clean river water out of it.
