I have a 94 wrx which i'm having problems with the boost control solenoid sticking open , i have cleaned it out with brake cleaner (it wasn't that dirty) but after about five minutes of driving it sticks open again leaving the car gutless untill i switch it off , sometimes i have to tap the solenoid for it to go back to normal .
Does anyone know how i can cure this fault or get around it
Thanks in advance

Matt

 

Buy a new one like I did...

 

Anyone got an idea on the price of a boost control solenoid?
