Welcome to 2CarPros.

Have you checked the coolant temperature sensor? It may be bad. As far as the oil pressure gauge dropping, how low does it get? Is there ever any noise from the engine when it drops low?

Take a look through these links and let me know if they mirror what you are experiencing.

Also, let me know if there are any oil leaks.

I will watch for your reply.

Take care,
