THis has happened to me in the past. My fix was to clean the throttle body. The problem began after my battery died. The computer was defaulted back to its original settings after replacing the battery. Once I cleaned the throttle body, everything was fine. This happened at about 85,000 miles.

It's the air measuring tube that will be clogged probabily.
In the air intake, you'll find an air measuring valve ( older models ) or a hot wire system ( newer models ).
See if the valve can move smoothly, and/or if the measuring wire is totally clean! CAUTION, those parts are very fragile!
The idle regulation valve can also be faulty or clogged ( or its tubing ). This specially on older engines were some oil is consumed...
