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.
