I 95% sure it hasnt been decatted, but it has had a k&n fitted... I cleaned out the boost solenoid tonight and its made a huge difference, however there is still some hesitation/ fluttering... I think I will give it another clean out tommorow night after the commute. And yeah i thought something didnt add up with your last post! Thanks for all your help, its much appreciated!

Ahh that makes sense! Its fine on idle, if when i go full throttle its like something cant keep up and the boost doesnt know what to do! I have a feeling actuator... How do i test that?

Great may seem like a silly question or im getting confused but why plug diagnostic wires in whilst cleaning? Purely just to hear it working?

I have the three port solenoid... So the restrictor should be in the bottom pipe to the solenoid? I have picked up some brake cleaner this morning so will set about cleaning the solenoid tonight...

I shall have a look see that the heat shield isnt touching! I couldnt see anything last night when i.looked that would cause obstruction! Thanks I will get some brake cleaner today and give it ago tonight! Do I start the car with the diagnostic wires plugged in?

I've been doing some reading, I would probably describe it as 'partial throttle, full boost', then when I go to full throttle the boost drops... Would 'partial throttle, full boost' be caused by the same problem as boost creep? No I havent done a the self code check.. been looking at how to go about it... I think I shall have to give it a go when I get a spare five mins. Also I intend to clean the boost solenoid soon... Whats the best way of tackling that?

Just checked, no movement in the actuator arm, could the actuator be faulty?

Yes I would describe it as that! I take it the actuator arm shouldn't have any play at all?

Hi All, I'm Andrew from Newcastle. I have just introduced myself over in the newbies section. Bought my first impreza, a '94 Import WRX Wagon a month ago. The car is generally very tidy and has been looked after, with no major rust or any severe mechanical problems. The car isnt using any oil or coolant. Anyway down to the boost problem. Here's a link to a video I recently uploaded to YouTube. https://www.youtube.com/watch?v=nwCe3crQu_0 The problem gets worse when the car is under heavy load and I have experienced fuel cut once or twice. Also if I lightly feather the throttle, the boost stays high and the car is like a rocket, however if I am heavy footed the boost drops low and the car feels like a diesel truck! I am completely new to subaru and turbo ownership, however I would say I was fairly competent at some home mechanic-ing (replaced engines etc). If I could rattle the brains of you more experienced owners at diagnosing the problem, I may be able to have ago at fixing it myself! Anyway thanks for any replies in advance! Cheers swanie999 P.S Sorry about the shania twain and shaking in the video!
