Hyundai Santa Fe Rough Idle Due to Faulty EGR Switching Valve

(30 reports)

On the 2.7L V6 and 2.4L 4 Cylinder, a defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

when ever i put gas in my car and only at this time after i m done putting gas in and i go to start my car it does not start right away it takes a few tries...every single time. -
I have a 2001 Hyundai Santa's skipping and running ruff to it start then about 50 miles it stops then later on that day it's does it all over again.. What is causing this....."Not the spark plug" -
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 -
Rough idling for a few minutes. Then it seems to smooth out after "getting used to the change in weather." -

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. -
misses at idle after it warms up and yes 29000miles on it -
EGR valve was replaced and still having the same issues and car is randomly breaking down at stop lights and signs. -

Rough idle, Check engine Light On, Code P0401. Have not investigated if it is the actual EGR valve, hoses to or from, or dolenoid yet. Pretty sure it had the same problem around 25-30 miles in 2005. -
