So my OG 9-3 is stuck at base boost (i guess), there's not too much power when i floor it and the turbo gauge will only go halfway.
When i got the car, it was stuck at base boost - diagnosed a bad BPC valve, changed it with a new one and i got full boost.
MAF was cleaned about 2 months ago, also change the DIC with a new one, spark plugs and also new vacuum hoses. Boost was fine, i had full boost, but didn't drive the car too hard for a while (only city driving). Last weekend, when i tried to drive it hard but it won't boost.
I tested the BPC and it's ok (shows 7 OHM resistance as it should and the air passes through it as it should). Also removed the hose from the wastegate to see if that works and it boosted into the red, hitting fuel cut. So i guess the wastegate works fine. I also tried resetting the ECU (pulled battery for about 24 hrs, pressed the brake pedal). Nothing works.
I won't know what to try next or what should i look for. I don't have open sid, ordered a USB cable (obdlink) a few days ago, still waiting for it to arrive. I have a bluetooth reader, i connected to the ecu and i don't get any codes or anything else. The car runs fine, idle is fine.
Any input would be appreciated.
