    Tumble Generator

    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 ?

    take the TGV housing out, physically remove the butterfly valves, leave the motors and the middle rod (or take the rod out), hook the motors up.

    Will this still work if the TGV motors are broken ?

    potentially not. You may be able to get the motors from someone who's removed them (particularly people who've moved on to different EM systems, as the stock one goes into limp mode without the TGV). Or, if you're handy with electronics, it could be a good time to tinker.

    Sounds like its time to get the TGVs deleted

    Never argue with idiots. They'll drag you to their level and beat you with experience.
