Twin turbo Posted September 27, 2014 Share Posted September 27, 2014 Hello does anyone know if acturator to intake air control valve (IACV) and exhaust gas control valve (EGCV) will operate during 4000rpm while car is in park/netural? I See no reaction from acturator and wondering if it is normal while car is in neutral or there or there is a problem with the vsv.what could be wrong Link to comment Share on other sites More sharing options...
Jos Posted September 27, 2014 Share Posted September 27, 2014 As far as I know they will only operate under load, so not in neutral? howmuch boost are you seeing and is there a noticable transition at 3700-4000 rpm? Link to comment Share on other sites More sharing options...
CanisLupus Posted September 27, 2014 Share Posted September 27, 2014 No reaction. It needs load to operate. The ECU shifts the point of activation according to the load(i.e.boost). Link to comment Share on other sites More sharing options...
Twin turbo Posted September 27, 2014 Author Share Posted September 27, 2014 Thats good news :)my only issue now is why i have a rough idle at start when engine is cold, it only last a few seconds though and idle is fine 99 percent of the time when engine has normal temperature,exept a little hikkup now and then.have tested that idle control valve makes that click when i stop the engine,or actually sounds more like 3 clicks.my car has only 25000km on the odometer so i belive that there is no deposit inside the valve.
