1 Lucky Texan Posted June 28, 2018 Share Posted June 28, 2018 maybe an injector is leaking? just seems like it's behavior is pointing to rich idle. or, IACV is closed too much ? 1 Quote Link to comment Share on other sites More sharing options...
eword Posted June 28, 2018 Author Share Posted June 28, 2018 I fully agree with the rich mix, no codes for injectors, did ohm test all ok, mechanic had nothing show up on diagnostic computer for injectors..... brb Quote Link to comment Share on other sites More sharing options...
eword Posted June 28, 2018 Author Share Posted June 28, 2018 Iacv is also suspect. Throws no codes, and half of my research on it says easy to clean, keep extra gasket handy, half says DONT EVEN TOUCH! I’d love to see it clean and verify function...

eword Posted June 29, 2018 Author Share Posted June 29, 2018 Ok... watched video on dumping sea foam into IAC valve hose, still in place on motor, to clean. Did, sounded better, but idle still surging especially when under load.. fan, AC, lights..... but WTF... there is an adjustment possible on IAC valve! So I simply opened the valve a few degrees until the idle smoothed out under load. It seems to idle a tiny bit high under a no load condition, I might adjust after this settles in for a bit....... ANYBODY KNOWS WHY THIS ISNT A GOOD IDEA, please let me know! I don’t want to over heat motor with too lean mixture, or whatever else I’m about to mess up! so far though, the feeling of another subie conquered is FANTASTIC! Thanks you all for your advice as I stumbled through this. SUBARU! 1 Quote Link to comment Share on other sites More sharing options...
