I have cleaned idle control valve with brake cleaner.stuck it back on the car its not working now ie valve plunger is not working back and forward so ordered a new one from subaru .would maf sensor be at fault as well.The car is my2000 Turbo owned by me from new

 

I am fighting the same thing on my Sti v3.
Did you also remone/clean the valve disc fron the inlet manifold?
Valve is clamped into position between the large valve body and the inlet manifold casting.

You'll find that many people on here recommend replacing the 99/00 MAF annually or at major service intervals.

Graham, I'm sure they're different valves the 99/00 is a coned rubber plunger type.

 

thanks for your replys 911 and houghton .I am getting a new icv.Then getting select monitor done to see if the maf is faulty.That will be the fourth maf in five years.

 

yep ICSV on STI3 and MY99/00 are very different.
Are you sure it's the ICSV? MAF sensor and Lambda failing can also result in lump idle and hunting of revs at tickover.

I had a problem with my car stalling when returning to idle revs turned out to be a combination of Maf and Lambda. (MY99 UK Turbo 2000)

The icsv not working ie plunger not going back and forward plus when turning ingtion on of it wont move back and forward.Noticed the problem when starting in the morning ie it would rev to more than 1500revs .The same when hot turn to start revs 1500 drops to 800 and sits

 

Oh ok dipsy, sounds like changing the ICSV is a good choice to begin with.
Not quite sure if the valve is supposed to cycle with the ignition, but it seems like a resonable assumption.

dannyboy i had the valve connected to the multi plug turning igntion of and on it was sitting coil pack so i see if it was working back and forward it was dealer told me to doo this so wasn't moving so new ones £237 this is including vat i will get sidc discount

 

OUCH Thats bloody steep for a solenoid, just bought an uprated clutch for not much more than that!

Have u tried somewhere other than a regular delaler for a price?
I would reccomend API Impreza or Grade A Subaru.

Good advice, I sold a perfectly good one on here, that I'd bought in error for the £50 that I'd paid for it.

You could also try the Wanted section on here.

 

I now its dear the dealers is 12miles from me so if there any problems i can take back in person .Plus buying from these person's named cost of deleviryIf its new or secondhand .i dont wont to end up same as i am no its alot of money .I am in scotland so most of the tuners up here are buying from the dealer so they be there bit on .I must have to much money ah ah

 

Fair enough you pays ure money and you takes your choice.

Hope it fixes it, and ure back out round those great highland roads soon.
