General Maintenance, Troubleshooting & Accidents.
I am having a very difficult time diagnosing my 2004 Automatic WRX and want an opinion from some expert Subi masters.
Problem: I am unable to rev past 4500 RPM, I get little (0.5 PSI) to no boost but I am able to hear my blow-off valve activate and my turbo spooling. I get horrible gas mileage...
