Unhappy Engine Revving Low

My engine is revving low.. does anybody know what can be a cause of this?...

if you dont let it warm up before you drive it and you come to a stop it will rev low and stall. thats pretty much what happens... any ideas?

I just read that idle problems can be caused by a bad Throttle Position Sensor (TPS)... do you guys think that it can cause the problem of stalling out when stopped?

It might cause if the throttle position sensor is bad it will rev high or low cause the butterfly valve will be stuck open or will not open far enough
