I'm a newbie to this 4 cyl turbo world so I'll try to explain in as much detail as possible! The other day I was driving along about 60 and I hear a click the cel comes on and the boost drops to -1 to 0! Ever since then the car will not boost over 0 and it accelerates like a non turbo car! The cel will come on and stay on for a while then just Go off! I took it to autozone when it was on and they said it wouldn't read the code and it might be a dealer specific code! The turbo still spins so I know it's not a blown turbo! The car is completely stock 04 wrx non sti! Any help would be greatly appreciated!
