    engine tends to bog down

    Hi, I got a problem. I have an 02 wrx, and it doesn't seem to be running like it should. I don't have much done to it, just a tbe and bov. But sitting at idle, it tends to bog a little bit and when I step on the gas to get going, it does the same as if it just doesn't wanna get going. But after that it doesn't bog until I get to a stop and of almost stalls. Rpms drop to almost 0. It also feels like I got some loss of boost. The air intake and maf is fine, turbo is not leaking either. Can anybody help me out please? Is appreciate it.

    Turbo XS. I have heard that it might make the car run lean. Any suggestions on a good not too expensive bov?

    It full atmospheric. I bought the car with the bov on it. And it runs perfectly fo.e when its cold and wet out. But I'm stationed out in Arkansas so its hot and muggy. And it doesn't seem to like it that much. What do you suggest? Should I get the stock bypass valve?

    Tune or not, you don't need it. Find a stock one, sell the TurboXS. You'll recoup money on it.

    Seen a few posts on this issue -- idle just drops to zero/engine shuts off, often when decelerating or at a stop light. Especially scary when you're in motion. Way beyond my abilities so brought it to my mechanic and he completely cleaned out the throttle body. Lots of gunk in there apparently (140k miles). So far running like a charm...

    In the other posts, someone else cleaned out the IACV and others suggested to reset the ECU afterwards.

    Hope that helps...
