crazy idle, limp mode.
 

Hi I have a 2004 hyundai santa fe with the 3.5. It has a intermittent high idle up to 2000 rpm and is in limp mode so it won't go over 3k. When it is ideling up high if I hit the break the engine will go "thump thump thump" and idle down to the point it almost dies and sometimes does. From what I'm researching I need a whole new throttle body but I'm pretty confused. The codes I'm getting are p1118, p1178, p1195. Thanks

Also really need to know we're the ets modual is located, can't find anything on it

Well no help from here but I figured it out and just wanted anybody to know that might have the same problem that it was the failsafe relay on the ect which is located below the ac contols, you have to that the center console out to get to it and a standard relay will fit.
