Hello everyone, i have some problems with my Mazdaspeed 3 bk, maybe you can help me.. i replace the turbo, everything was fine, couple of months after replacing i notice that car one day going very well, (slightly over boosting, faults in picture below ), i found that one hose for wastegate solenoid valve isn't attached to intake hose, i connected that hose, car was smooth again but not for long and it started twitching and jerking at aprox 2500-3000 rpms at steady throttle position, it have hesitation when accelerating, and i think no boost or very small boost, no fault codes now..any ideas what to check for? Car is bone stock
