Engine surge at idle

[rebuild 68]

I have A -93 with auto at idle the engine revs on its own as the car wan'ts to take off on its own. Anyone know what could cause this?

Try cleaning the throttle body paying attention to the idle air circuit with one of those spray can cleaners you can get at a parts store first.

Are you getting any codes??? I had a similiar problem last week but was getting a code 44. Replaced the o2 sensor, reset the computer and all ok.
