I have a 92 camry automatic with the 6 cylinder motor. It drives great except for recently it started jumping. It does it when i am at a complete stop and try to take off. As soon as i give it gas the car jumps forward and backs down and jumps forward again and then calms down. The rpms go from like normal to 1000 rpms more, back to normal, and back up a 1000 and so fourth until i get to about 10-15 mph then it drives normal. Any clue guys?
Thanks in advance.

Might be the Intake Air Control (IAC) valve or MAF sensor.
