You has a vacuum leak on the engine.
In order to troubleshoot this, you must start with a clean engine wipe down.
The major offender parts are
air intake gasket on the manifold
air tube after the mass air flow sensor
rubber seal under idle air control IAC motor

Warm up the engine for 15-20 minutes (LEAVE THE engine at idle) then spray a little Barmen carburetor clear on the potential air leak location (ONE AT A TIME) and listen for a surge in rpm.
If the engine speed go higher that's mean the carburetor clean (ADDITIONAL FUEL) got into your engine and that's the gasket you need to change.
There may be multiple leaky spots so take your time and check all rubber gaskets,sensor and hose that are lead into the intake manifold.
When you finish fill up with one tank of Chervon to clean out the injectors.
Please post more information after your inspection.

Idle air control could be stuck. If so clean it with some carb and choke cleaner. EGR could be stuck partly open. If so clean that or replace it.
