    TMIC Leak

    Just wondering if a TMIC leak is harmful to your car, I can hear the leak or alot of air being pushed in while boosting, then when I come off the gas I get loud backfires.

    If it's a big leak it could throw a lot of stuff off even if you aren't boosting.

    Uhh you have a 2013, take the car to Subaru. My guess is you blew off either the intercooler to throttlebody hose or the bypass valve to intake manifold hose.

    i had the hose from the tmic to throttle body come off on mine. made the car run really bad. i couldn't boost at all.

    it takes less than 15 minutes to take the tmic off and inspect and then put back.

    Well I know where the leak is from, its from the hose that runs from the TMIC to the throttle body, inspecting the hose it shows no damage, it just slipped off.

    My leak was so bad when i tried to boost to diagnose it completely denied my in 3rd at about 45k, almost like it hit a fuel cut.

    Yeah.. that could definitely do some damage to your engine. If you want to make sure it sticks good, spray the coupler with a little hair spray before popping it on.

    Fixed it! Couldnt get the hose on but a little canola oil (not too much) just to slip it on and good as new, boosts like a champ, and also fixed my backfire.
