    Hey everyone! Hope everyone is doing awesome! I am in need of a little help. I am on my honeymoon in Harrisonburg va but Stella (my r53) is trying o make my life difficult. I think the throttle body is shot (so ill buy someone's extra) but here are the symptoms: wont hold idle. Studders when at a cruising speed. Eml light comes on for about 15 seconds on start up. Seems to be greatly losing power but wot seems fine. Traction control automatically turns of and locks in the off position. Any help would be greatly appreciated. Ps I had a leak that allowed water in behind the dash on the drivers side. I fixed it and this happened after. Idk if they are related.

    Thanks all!

    I think you may have identified the source of your problem (the water leak behind the dash) but I can't tell you what to fix......if it's leaving a code you can stop by any chain auto parts store and have them read it for you, that might point you in the right direction......good luck!

    If I had to make a guess I'd look for corrosion, especially on a ground connection.

    And congrats on your marriage.

    Ill get the numbers ASAP. But Codes keep jumping. I had lean condition 1 count. Map sensor error 0 count. Throttle plate error (or something like that)
    The other that popped up and then disappeared was a 2/3 torque reading. I took the intake intercooler and all accessible top plugs off and saw nothing odd. Put it all back together and it ran great for one day. Now it's all back

    Double check all your battery connections, especially the grounds. Don't forget the short ground cable by the right side motor mount bracket.

    Battery

    If you're in a pinch, try disconnecting the battery a while and let the computer relearn Stella. If that doesn't work, try some Pino Grigio on the new bride. Works for me. Good luck.

    Sounds like you're moving in the right direction. Check that sensor connections are plugged in, too, like the accelerator pedal, the throttle body, and the camshaft position sensor.

    Also check the fuse box (engine compartment) to make sure all the relays are well seated. Sometimes they can vibrate a little loose.

    When my throttle body went bad on my R53 it would randomly go into limp mode with a CEL and EML light on. it did lock the traction control off one time though. whenever it would do that I got by for the longest time by pulling over unplugging the throttle body cable and plugging it back in.
