Hey everybody, 
  
I just got a 1990 Subaru Loyale a few days ago (will post pictures soon), while driving the check engine light turned on. 
  
It turns out it is a ISC Solenoid Valve Fault. 
  
I'm just wondering if anybody else has had this problem and what you guys did to fix it. 
  
  
EDIT; my bad guys, i was looking at the wrong codes    After looking at the correct codes the problem is in fact the  Idle Air Control Valve or Circuit.
