I need some help in finding options to fixing the Tumble Generator Valves in both of my WRXs.
Blue WRX- At 140K miles my TGV triggered the CEL, then at 155K the car began to run rough. Dealer recommended to disconnect the TGV and shortly thereafter the car runs really rough intermittently.
Black WRX- At 180K miles the TGV issue has a CEL but no rough running yet. Lucky for now
How does one get rid of or fix these TGVs in a cost effective manor ? Does anyone else have this issue ?
