If the car is already warm at night from hitting stop lights etc, my gauge quickly goes down when i just continuously cruise.

Im thinking a temp sensor? If anyone has any advice and any idea on how much it would cost it would be appreciated.

Thanks
Do you want to know how they came to that conclusion and why they're so sure?

Do you know what your cooling system is doing to make it do that?

Just asking cause sometimes it's interesting to know these things. Makes you appreciate how complex yet simple an engine is.
