ash96wrx Posted May 11, 2014 Share Posted May 11, 2014 I have a 96 impreza wrx turbo I haven't driven it for a week. Went to take my mate out in it and was very hesitant Rev's would drop to nearly 0rpm when clutch dipped. Seemed like it was starving herself of air then suddenly pick up. Just had new start is going in for cambelt etc change in the next week or so.. any idea's guy's :) Quote Link to comment Share on other sites More sharing options...
Gambit Posted May 11, 2014 Share Posted May 11, 2014 I'm going to say the Maf mate if you pull the Maf cable off whilst it's running if it doesn't stall it's a sure sign it's that. Have you read the codes at all see if it's throwing any up. And welcome to S.O.C 1 Quote Link to comment Share on other sites More sharing options...

ash96wrx Posted May 12, 2014 Author Share Posted May 12, 2014 Would it be worth buying a cleaner and try cleaning in. I know they are fragile and you need to be careful But worth a shot for a few quid surly . what do you think Quote Link to comment Share on other sites More sharing options...
Gambit Posted May 12, 2014 Share Posted May 12, 2014 No worries mate. And you can try clean it but I've had 0 success when I have tried in the past :( Quote Link to comment Share on other sites More sharing options...

wrxweston Posted May 12, 2014 Share Posted May 12, 2014 Id say maf mate ive got a 97 turbo and i had same issues sometimes would also cut out at lights. Replaced it today and its worked wonders ! Idle and throttle response is spot on. I am the sort of person that would rather replace then try clean but that's just me. Mine set me back £120 delivered 1 Quote Link to comment Share on other sites More sharing options...

Gambit Posted May 12, 2014 Share Posted May 12, 2014 How to ECU codes Here you go, this is what Savage was on about :D Quote Link to comment Share on other sites More sharing options...
ash96wrx Posted May 13, 2014 Author Share Posted May 13, 2014 Would it be worth taking the icv off and give it a clean. Also is it located on the right hand side. As you are standing in front of the car.. Quote Link to comment Share on other sites More sharing options...
stants Posted May 14, 2014 Share Posted May 14, 2014 Depends which version you have, some are on top of the inlet next to throttle body and others are on the right but on the back side of the inlet manifold, like this In either case get new gaskets before you do anything. And if it's the latter of the two try and get hold of the diaphragm that goes inside. Google subaru idle air control cleaning. Will give you both walk through guides.

stants Posted May 14, 2014 Share Posted May 14, 2014 Oh and don't undo the bit on the top without marking the screw locations. You shouldn't have to remove it to be fair but if you do mark it 1st other wise your idle will be all over. Quote Link to comment Share on other sites More sharing options...
ash96wrx Posted May 14, 2014 Author Share Posted May 14, 2014 That's exactly the same as mine.. the gasket are a couple of quid aint they... Quote Link to comment Share on other sites More sharing options...
