im throwing a code 14 and 20 on my si motor wut do i do to fix this?

 

thats for ure iacv...
it is located on the back of ur IM right next to the throttle body...there are two coolant lines that go through it...take it out and see if it is clogged up...
if it is then clean it out and u should be good to go...
if it is not clogged then u should check it for continuity...if it is getting power then u need to replace ur iacv...id say get one from a junkyard because the dealer costs a grip
