You could start by cleaning out the boost control solenoid,there are plenty of pages on how to do this if you type it in the search bar at the top of the page. Then it might be worth you checking all you hose, making sure that there are no crack/splits in any of them.In fact if you have not had the car long ,it might be worth checking plugs,air filter ,fuel filter,etc 1st to start off with then post up your findings .Also do you have the same issues when you drive the car with the power switch on the side of the gear lever switched on.

hi all
done all the usual obvious stuff and still the same also just been told may have been looking in the wrong place could be the auto box jumping in and out of gear not all the time and only starts above 3500 anyone heard of this?

Could be the MAF.

Hi i have a 1995 wrx auto and i can guarantee you its not the gearbox dropping in and out of gear, when the gearbox is low on oil or lets go it usually rips the high clutch to pieces and leaves you with no drive at all, its all or nothing thats it! Anyway it sounds to me that you may be getting overboost, this happens easily on an auto especially if it has a decat. Or failing that it can also be the maf, if the maf fails it will cut like hell over 3000rpm and the boost will be very unstable (constantly up and down). Do you have a boost gauge fitted?

mental101

hi
i will get a boost gauge sorted i have changed the maf cleaned boost solenoid air filter ect never thought of overboost as i thought the check engine light would come up and the car would cut out like it did on my legacy gt.

gonna go down the route of changing all the vac pipes now ill keep you posted

mental101

hi all
changed vac pipes and connected a boost gauge and its boosting to 18psi sometimes 20
so i am overboosting any ideas on how to get my boost down it is standard no boost controllers are fitted thanks

mental101

also would fitting a manual boost controller do the job turned down to about 10 11psi

mental101
