when I start my car, it idles just below 1000, but after a few seconds it gets slower and goes down to around 400 or 300 rpms. this only happens when i start it and it goes away after i wait or drive for a minute. but when i drive with it, i will be stepping on the gas, but nothing happens and then it kicks on and it does this for about a minute. could it bethe 02 sensor?

Yeah I'm down around 500 or 600. If you need to adjust your idle, there's a small screw on the throttle body that goes to the throttle linkage. Just turn it a little with the engine on till you get to the desired rpms.

check how your alternator is working. Or your O2 sensor is out. Have you changed your oil recently? you could be overdue

I have just changed the oil about a week ago, but since i have had the car and even nowit still idles really bad and jumps ONLY when i start it and only for about a minute. it normally idles at 700 or 800 but when i start it it gradually goes down and it sounds like crap. then when i press the throttle, it gets really jumpy and half the time doesnt even go, then it goes after a minute. if you need me to explain it more please ask because I would really like to get the car working normally

Does the car kind of stutter when you hit the car?

This is the problem many experience when changing their spark plugs to the platinum ones. In my case I get this because my plugs foul. Take the car and let it warm up out on the highway. If the stutter doesn't clear up I would replace the spark plugs with the OE Bosch +2 coppers from the dealer.
