My scan tool displays 36 different live figures but I don't think one of them was coolant temp unfortunately.
Still wondering if your problem was fixed? I have the same issue. Lost 10-12 mpg instantly. It makes no sense that people say battery on an...
I do not have any codes, both sets of plugs are original heat range plugs. As far as torque they should be right around the recommended torque....
The plugs all look really good. They all look new yet. That's why I don't know about the potential wire issue since none look different. Yes same...
