I've recently developed an idle problem that is more annoying than anything else. When I start the car while its warm, the idle will drop to around 500-600rpm and then go back up to normal after about 5 seconds. It will continue this behavior every time I go back to idle (like if I take off in first coming up to a light, then put it back in neutral) for about a minute after turning it on. Could it be the IACV?

 

Not sure, but I have the same thing...I've learned to live with it..don't know if it's normal or not.

 

u think thats bad.. my **** idles at 250 and I dunno how to fix it.
