help needed???

flew down to westo super mare yday. cruising down the motorway at say 80mph cars fine , but if i try to floor it hard (straight to the floor) then it sort of kicks back at you,sort of looses all the power? only for asecond, but if you floor it gentely then its fine , does it in 4th as well,but like i say do it from 80 to 130 softly then its fine !!!
did ask at subaru but they lost me, said something about a duty solenoid ,and even said about a bloked ppe? cant see that though as it would be at any speed in any gear. if you boot it off the lights ,say in first to 4th then no problems?

asap folks....

oh its a 1999 uk spec 2000 turbo 87k

its overboosting, basicly ecu is detecting to much boost pressure comming fromt he turbo and forcing it to back off.

prob suddenly doing it cos of the cold weather

had this with my car just last week, boost solenoid was sticking open, follow the thread for cleaning the solenoid, or try connecting the green conectors under the dash and listen for it clicking first

of its not the solenoid then might need remapping to sort out or an ecu reset could make it accept the colder air, worked on my mcrae when it overboosted after running on air temps of -3 lol
