could be a throttle sensor, but I would get it looked at. Your car needs to be scanned to see if there is any fault codes

Check the IACV, your fuel filter, and especially all your vacuum lines. It really sounds like you have unmetered air coming in somewhere. You can also try re-grounding the MAF (Mass Airflow Sensor) and/or cleaning the MAF - just remember not to use anything other than MAF cleaner to do so. If none of that does the trick, then check your TPS (Throttle Position Sensor).
