motor loads when clutch pedal pressed

[CarPsyco84]

This is something new, that I haven't seen before... The engine becomes loaded, like you just turned on 8 head lamps, when you press the clutch pedal down... Doesn't do it when the engines cold, but the warmer the engine is, the worse it gets... I had to raise the idle or it would die when you press the clutch pedal down... I'm thinking/hopeing throw out bering, and not some motor issue, makes no audible noises either... I'm baffled
