warm up normally if it's idling, but when I start driving it cools back down. If I'm on an interstate or expressway, the needle will drop down to the cold like it was never warm..i am at a loss and want to kill this car i have changed t stat thinking that was it and it still cools off to where i can drive it for 30 minutes down the highway i can stop and pop the cap off and the coolant is cool but i have heat and it warms to normal when i stop at a light until i take off and it gets luke warm again and cools back off
