and I have had idle problems (rough, hunting, stalling) for years...

I have too the check valve assembled... but my question was actually theoretic.. Would it be so easy to find faulty ISV ? My ISV let air trough both way like an empty tube if I blow into ? :shock:

...I think the ISV is too big to blow through... what u mean ? :shock:

Every one talking about leaking ISV but noone can answer my simple question :?: :(

So...if I take ISV off... anf blow inside the "thing" Should it be absolutely tight if ok ...no air leak trough it ? :shock: gee60

it "works" but feels sticky and response time is quite slow... cause hunting idle sometimes... I have jiro-valve assembled...

Every time I start the engine (even blue sensor hot) it runs few seconds (20s-1min) over 1000 rpm at idle...so there must be some sort of timer in ECU that keeps rev higher than idle set ...any idea :?: gee60

Hmmm... cold enrichment temperature sensor = blue sensor ?? gee60

Just want to know where from and price :?: Gee60
