Hi there,
Thanks for reading. Here's my problem, I have a 94 Ls and recently, I've noticed my temp. guage has been acting weird. When I'm idling my guage needle goes to the normal operating temp. mark. As soon as I start driving the guage drops significantly indicating the engine's cool, but it's not.
Also, my heat is affected by this. When the engine idles I have heat, but when I start driving there is'nt any heat. The coolant's levels fine with no leaks. Does anyone have any idea why it's been doing this?
