when i drive on the freeway my rpms seem pretty high for driving just at 60 or 70 mph. they are at or above 3000. if i let go of the gas pedal and coast the rpms drop down immediately to 1000 rpms and when i push on the gas again the engine doesnt start picking up speed until the rpms reach where i left off usually around 3000 or 3500 rpms. what could be causing this. the engine and transmission both work great. is it a big problem or nothing serious. thanks for looking
