Your car might be able to tell you whats wrong with it , follow this instruction

gone into limp mode need to get the fault red code

 

Connect your green n black connectors under the dash turn ign on for engine check light flash codes, see if there's any codes in there, If your not sure how to do this or don't know the codes, look in the "how to section" on this forum. see wot you get? go from there mate! or follow link from jay jay, nice 1 jay! cheers!

 

What fuel are you running the car on? (ie unleaded/super unleaded/vpower/tesco99 etc)

Incase you couldn't find what jay jay was trying to show you (I think) this is the link to the correct page's for reading your fault code on your classic and the codes key.

Thats what I'd check first.

 

Any modifications?

Tony

 

No modifications and the fault code reads iac valve fault

 

Hmmm looks like a new one is about 300ish quid, 475 from a main dealer
Have a read of this topic

Funny that, sounds a bit like mine. Starts fine, drives for about 5-10 minutes and cuts out, starts fine again and doesn't do it anymore, but this happens everyday pretty much. Mie's a P reg WRX.(SILVER).

 

Am I right in thinking that we're talking about the (usually) creamy grey coloured plastic idle control valve on top of the engine air inlet manifolds? Because if we are I'd recommend giving it a clean, reset the ecu (20 min battery disconnection) and then try it before shelling out that sort of money .
All I did with mine when I had problems was disconnect the battery, check the wiring (all good), unplug it, (note position as is adjustable) then using a phillips head screw driver undid the two small screws and removed the top half from the car. Then using some brake cleaner, sprayed the metal inside, scrubbed over with a wire brush, then dryed. Also I used the brake cleaner on a cloth and cleaned the rod in the centre (part left still on the manifold) using the wire brush again. I left it to allow the brake cleaner to evaporate then re-fitted it in the same position, connected the plug and re-attached my battery. Might be worth trying before spending the cash

 

Yup clean it first, cheaper than 300+ quid

Crazy money isn't it The joys of Subaru ownership aye' Tony
