I know theres a lot of trouble out there with bad idles suffering from this problem myself and having no fault code I can understand everyones frustration I see theres a lot of fixes out there from o2 sensors vacuum leaks idle air control motors theres so many to choose from trust me ive tryed them but my advice is before you buy all that stuff check the egr ports there easy to find there located in the elbow behind the throttle body to see if there blocked with carbon if they are easy to fix clean out with some brake cleaner and to tooth brush also good opportunity to clean the idel air control motor at the same time that can get carbonated too its a nice and easy plus cheap fix hope this is some help to you guys

 

Replace TPMS sensor & glow plugs. Call the job done

 

Huh? Where are the glow plugs located on a gasoline engine?

 

Typically the glow plug is somewhere between your gas magnets and the exhaust whistle, though in some models its behind the engine alignment regulator housing.

 

lol at least mike caught my drift. I was just trolling
