I will also add that grounds are the root of all evil. I also never run my fans while in motion, my car runs about 184/186 and I only need my fans if stuck in traffic (Florida). Your oil must be 159 at minimum so you def need some heat.
I personally don't think anyone should be on an amp gauge anymore.
P.S... The only reason I mention my experience is to add a data point and to illustrate that this car is a good car. I stretch the throttle cable every time I drive it, it has all the updates and it's a very good and reliable car. Granted, I just drive into town and back most days, but still, it's treated me very well.
