Rough idling for a few minutes. Then it seems to smooth out after "getting used to the change in weather."

Rough idle when engine is cold.
2010 Hyundai Santa Fe - 2.4L 4 Cylinder 99,500 mi,
Engine vibrates when stopped in gear. Sometimes I feel hesitation when leaving from a stop. Gas mileage is down. New plugs and could have been installed. The intermittent vibration persists. I'll be having the dealer put in a new egr switching valve this week.
My Sante Fe also has a very rough idle but haven't had it diagnosed yet.

my eco light flashes then goes off and motor runs rough when at a idel for stop sign or red light the gas milage is so poor about 10 miles per gallon. the rpms stay around 2.5 and jump to 3.5 if you excelerate as to pass a car the rpms go as high as 6 and never come down pass 3.5 ??? the shop changed the throttle body stating this was the issue but i believe there are more than this .I think the shift tronic is the issue. i requested they change the egr switch seeing the car is still under warrantee but they were sure the throttle body was the answer so we will see in a day or so once i get my car back from shop if not it goes back and they will continue to play hit and miss till they find the problem untill then i drive a brand new fully loaded 6 cly santa fe as a loaner Beautiful car nice ride love it

Check Engine light is on. Engine rattles during acceleration. Engine has trouble idling. Engine has trouble starting. Exhaust fumes in car.
This has been a reliable car - we got it at 26,000 used from the dealer, but I tend to have the same problem during warm weather. I have been using a fuel conditioner just to keep it running smoothly. I thought it was the ERG valve, but I had it changed today and still have the same problem. Going to have the fuel filter checked next.

2015 Santa Fe shutters after it has been come to a stop and been in idle for at least 10 seconds. It's covered in warranty so we'll be taking it in to the dealership.
