I would start with the following:
Check for engine codes (the check engine light might not be working)
Check for vacuum leaks
Check the coils
Check the IAC valve
Check the EGR valve
Clean the MAF sensor
The spark plugs may need to be replaced, check the plug gaps
Check the air filter (general maintenance)
Check the PCV valve (general maintenance)
