Today I noticed that when I'm pressing on the accelerator a little (enough to make the engine respond and increase in speed) the rpms on the tachometer don't rise. I don't think it's an gauge problem. When I push it more the rpms do seem to pop up quickly. But if I'm pressing the pedal enough for the car to increase speed, shouldn't the tachometer show the increased RPMs? If the Vehicle Speed Sensor was bad wouldn't it not show anything at all?

Thanks for any ideas you may send my way!
