Earlier my car just went down to 500RPM and felt like it was going to die and the check engine light came on, i had a friend scan for the code and it came up sayin Something wrong withthe IACValve. Has anyone else had this issue or know what to fix?

 

did it only do it once or is it still doing it?

 

So far only once

 

if it has not done it before or since then, you might just not worry about it. just a little hiccup for your car.
