Say you're in third gear going in a straight line with no need to stop. You let off the accelerator and downshift to second gear then coast with no pedals in use. Will the car reach a certain RPM and then stop decreasing, making the car crawl forward at a slow but steady pace? Will the car keep decreasing in RPM until the engine doesn't have enough torque to continue running, resulting in a stall? Does it depend on the vehicle in question?
Once you've started the car from a full stop, will the engine ever stall, assuming fuel isn't an issue and you don't touch the pedals?
I'm asking because my car will not stall in first, second or third gear on a flat surface. I'm just wondering if there's something wrong with my engine or transmission or otherwise. For clarification, I drive an Acura RSX Type S, so it has a pretty high strung engine which is where my concern comes in.
