alright. so tonight i let the car idle for maybe 20 minutes just sitting in it doing nothing. well, i put the car in reverse and gave it some gas, and this HUGE cloud of smoke came out. I was like crap, but it didn't do it again. It was night, so I couldn't tell what color it was, but it smelt like burnt something. So anyway, I go to my friend's house, and turn the car off. Come back out about 10 minutes later to leave and restart the car. Smoked just a little bit but nowhere near as much.

Now the part I need help with. What are the possibilities of what this could? The car idles to 1.5k every now and again when the clutch is depressed, but then drops to around 1k once the car has been driven for a bit. Not sure if that's significant or not. There's no coolant loss, and no real oil loss that I can see. Please help me, this is ticking me off.
