"I read somewhere it could be the knock sensor? Another thing Ive noticed is rarely seomtimes when i turn the car off in a parking lot, come back to it withint 5-10 mins turn it back on and pull out the parking lot and step on the throtle a little the car gets confused, as if it doesnt know Im pressing the gas, and then all of a sudden its like it catches and then takes off."
That seems like a throttle position sensor problem.
There's a test guide for it here.

Is the miss at idle more than 50 rpm? Is there no error code or check engine light?
I've also been told that throttle shaft bushings can be a problem if there is too much play.
Anyways, Good luck!
