Harryburgundy Posted June 15, 2014 Share Posted June 15, 2014 Hi The idle on my newly acquired 1996 2.0 Sport has started to idle slightly erratically. Normally it will sit around 700_800 but I noticed yesterday that on a few occasions it sat at 1200. Despite it age the car is low mileage at 36k. Could it be something as simple as a return spring thats a bit dry? Just thinking out loud...I haven't got a clue :-) Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 15, 2014 Share Posted June 15, 2014 Was it cold like starting it in the morning it's normal for it to be a bit higher But gives the ECU a read see if it has any codes best bet to start with :) http://uk.subaruownersclub.com/forums/topic/2366-manually-reading-ecu-codes/ Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 15, 2014 Author Share Posted June 15, 2014 Thanks again...but...the check engine light does not come on at all. !Removed! Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 15, 2014 Author Share Posted June 15, 2014 Oh and btw colder starting is fine...couple of turns and she sparks up Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 15, 2014 Share Posted June 15, 2014 I would still read them just incase the bulbs had it. But I would pull the plug off the MAF see if it stalls. I'd say most of the bad idle problems will be MAF related :( Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 15, 2014 Author Share Posted June 15, 2014 Thanks again matey...I will Google your reply and see what it means ( I am such a newbie to car stuff). :-( Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 15, 2014 Author Share Posted June 15, 2014 Ahhh...mass air flow censor. Yup I have seen that lol Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 16, 2014 Author Share Posted June 16, 2014 Right...today I am going to see if I can read the codes. I also thought about cleaning the maf sensor. Do you know what size security torx drive I need? Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 16, 2014 Share Posted June 16, 2014 Sorry mate should have just said you get used to just using abbreviations of the names just automaticly think people know what you mean :) I'm not too sure on the size sorry and cleaning doesn't always help. Well I've had it before the MAF ( <I will use it now :) ) problem tried to clean the 1st one didn't help at all their very sensitive. If someone has used a filter like a K&N oiled reusable filter thats enough to kill one so if it is that check the air filter too. Anyway so I got a 2nd hand one of eBay same problem bought another dead MAF :( This was all without any ECU light on so was guessed. Bought another one not cheap :( and like magic it worked :) Other things that can course it though is any split or broken lose pipes would need a water spray and carefully go around the rubber hoses. Spark Plugs and coil packs or the leads if they have gone will be rough idle too. Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 16, 2014 Author Share Posted June 16, 2014 Nah...no need to apologise. its fun trying to work it out. Well..wiring isn't easy to access...think the green ones were higher up the loom as I could just them. These are the black ones I connected... do they look like the right ones? Nothing on the dash so I guess the bulb is blown.

Gambit Posted June 16, 2014 Share Posted June 16, 2014 Yep they look like the ones mate :) Person who sold it might have removed it which is a bit naughty. Might be worth having a look :( Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 16, 2014 Author Share Posted June 16, 2014 Thanks again matey. Yes, my cynical head did ask the question ' I wonder if the garage removed the bulb to conceal a fault? ' I will ask him on Wednesday when I see him, I read liars pretty well. Anyway. Let's get to the bulbs. As far as I can see the plastic casing holding a few switches is held on by four screws. Unbolt, pull back, undo switches and pull off ( although I do have an aftermarket cobra immobiliser there which I am keen not to disturb) Them another four bolts to remove the instrument cluster. I am guessing the speedo is cable? What happens next I am not sure Quote Link to comment Share on other sites More sharing options...
bang Posted June 17, 2014 Share Posted June 17, 2014 I also had this problem. is the MAF sensor. carefully reading it wrong sends incorrect information to the ECU. you could have a rich or lean fuel mixture. in 10 years I have changed maf sensor 7. I now have a racing ECU that has been permanently deleted 1 Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 17, 2014 Share Posted June 17, 2014 Yes mate its pretty easy to get the speedo cluster out. On'y problem you might have is the length ...... of the wire :) Just unclips from the top might be 3 if memory serves me right, and then removes easy enough all being well.

Harryburgundy Posted June 17, 2014 Author Share Posted June 17, 2014 Just seen this http://www.ultimatemods.co.uk/subaru-impreza-93-99-dashboard-led-bulbs.html but I am unsure if it contains the correct bulbs for me Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 18, 2014 Share Posted June 18, 2014 I'm not sure but been tempted to change mine so might give them a shot myself :D Quote Link to comment Share on other sites More sharing options...
Harryburgundy Posted June 18, 2014 Author Share Posted June 18, 2014 Would you Adam and Eve it...the Check Engine light has started to light up on ignition. Not all the time ...yet!

Gambit Posted June 19, 2014 Share Posted June 19, 2014 Well I bought some of them bulbs to try got the heater controls too :) makes me think more to the MAF sensor going that. But have seen it turn out to be other things :) So still hard to know for sure. Quote Link to comment Share on other sites More sharing options...
