Bondy Posted January 25, 2009 Posted January 25, 2009 Hi everyone hope ive done this right as im a newbie I have a sick Impreza AWD that has a miss fire, i have put it in for service and its no better. Then onto a rolling road to check the set up , on idol its reading where fine but on boost the readings went through the roof . Has anybody come across this before or do you know of a good Scooby garage Cheers Bondy
m@tt untimate STImulation Posted January 26, 2009 Posted January 26, 2009 dont wana scare you but if its a coff or a jerk it could be bad, i thort mine was the boost solinoid getting cloged with oil and ended up it being head gasket is it drinking oil and hows ur coolent level?? hows the running temp?

No all thats fine not drinking any oil and temps fine Any more ideas mate Bondy
m@tt untimate STImulation Posted January 27, 2009 Posted January 27, 2009 im new to this aswell so not 2 sure i think i may have a similar prob, i needed my headgasket doing i get it back 2mo so will let u kno if its cured it, could be the coils to the spark plugs.
m@tt untimate STImulation Posted January 27, 2009 Posted January 27, 2009 when i talked to subaru they rekoned it was the duty solinoid (boost) ring them and c 01732870386. ask for service dept and explain the runnin issues u r having. how is it to drive????

Yes mate i got told it could be a coil pack breaking down but will have to wait and see , whos dealing with yours ?
kentperformance Posted January 27, 2009 Posted January 27, 2009 Yes mate i got told it could be a coil pack breaking down but will have to wait and see , whos dealing with yours ? The coil pack is fine on it, but it has a definate misfire on idle when it goes down on one cylinder. Old fashioned mechanics tracked it back to the lead arcing out. The were no codes in the ECU, and a reset made no difference either. Once the leads are on that should be it. I would expect the boost soleniod to either throw up a code, or show overboost or low boost tbh.
m@tt untimate STImulation Posted January 28, 2009 Posted January 28, 2009 mine has individual coil packs i am goin to try that and the leads

The boost solenoid will only throw up a code if it fails electrically not if it is clogged, also it fails safe it is more likely to limit boost to wastegate pressure 0.5 BAR, an oil contaminated solenoid and/or boost control pipework will cause hesitant boost control without CEL indication.

With no code in there, it does not show either high or low boost, and none other the other symptoms, so was ruled out.
m@tt untimate STImulation Posted January 28, 2009 Posted January 28, 2009 cool, mine is still playing up im goin crazy, only under load, i get problems where it seems like the boost drops off?? its hard to explain, also it doesnt start strait away. thats why i think it may be coil pack or packs

m@tt untimate STImulation Posted January 29, 2009 Posted January 29, 2009 will do let me kno how urs goes
