When I'm driving and come to a complete stop my idle will stay at around 1100-1200 rpm then stay there for a second and very, very slowly drop back to normal idle around 700-900 rpm range. Any ideas on thsi guys?

 

idea anyone????

 

Good question. I have a problem like that too.

 

maybe need to clean your IACV and check vaccum.

 

i did it couple of times already, clean the iacv that is, but it still returns too slow. From say 1300 then it will slowly go to like 900.

 

maybe you need to clean your throttle body because all the grime and dirt thats built up might be causing the throttle plate to close slower

 

your throttle cable might be sticking too, mine did that b4
