New to the site but thought I'd share this. Try Bangood.com for parts, just bought a new IACV Solenoid for the Forester for $12 with free delivery. Not much to lose if it makes the engine idle perfectly again, cleaning worked ok but still idles a bit low.

Welcome Dinga111,

  Idle control solenoid. Good idea. I would imagine that would assist with proper idling. "Still idles a bit low".

 Hmmmm. Let me think now, Spark plugs, air filter. HEAD GASKETS. I had an issue with the head gaskets, an INTERMITTANT issue, causing idle problems at random  times, culminating in troubles after it warmed up fully.

 had to change those head gaskets.( I used Cometic triple/multi layered steel heaf gaskets. The best, except for maybe JE Pistons brand. )

 Whereby, sometimes the idle was fine. THEN other times not so much. Fluctuations. Sometimes high, sometimes low.

 I think Ted Nugent sang a song called Stranglehold "sometimes you gotta start high, sometimes you gottta start low, some people think they're gonna die some day,

 I got news you neva got to go........." . 

I almost thought your username/handle was Dingo. Sorry for my confusion.
