i recently purchased this car and ever since i purchased it when i turn it on the rpm goes to 1500 to 2000 without accelerating in parking. once i shift into gear it will go down to 1000rpm. i have cleaned the throttle body as i was told it could be dirty but it does the same thing.

Check all vacuum lines for leaks, also remove and clean the IAC (Idle Air Control) valve.
