    2008 WRX Losing Power

    My wife was driving her 2008 WRX late last night and the engine suddenly lost power. She had driven 20 highway miles and the check engine light came on and the “cruise” light began flashing. She didn’t have far to go and it was 10 degrees Fahrenheit so she limped home.

    I tried it today and it is still running at about half power. There is also a “whirling” noise that is not normally there.

    We live in the country and don’t have a “trusted” mechanic close by -- so any input before we have it towed somewhere would be appreciated.

    It has 114K miles on it and, other than regular maintenance, we have had no problems with it. The battery is new and all of the fluids are OK.

    Thanks in advance for your help!

    Very difficult for us to diagnose what's going on. The car entered "limp mode" to protect itself, but there are a variety of things that could cause that. Do you have any way you can get the CEL code read?

    I just got a referral for a reliable mechanic. My previous one moved out of town. Is it possible for me to drive it 6 or 7 miles safely?

    If you drove it very carefully I would think hat you could make it. Without hearing tho is the concern.
    This safe mode is designed to get you safely to a shop or home. I would however use your best judgment. If you have towing on your insurance or aaa use it and be safe.

    Those 6 or 7 miles could mean the difference between a car needing work or a car needing an engine replacement...if you don't know what it did to lose power, I wouldn't drive it anywhere, especially without knowing the codes thrown.

    Whirl noise makes me think intercooler hose came loose or is cracked/damaged. If this is the case, it should be ok for a few miles but, change your plugs as they may foul out from running rich in limp mode.

    Good luck!

    If you start your own thread you may get more input...not nice to thread jack

    Again though, no one can really help you without knowing if there's a code or not. Assuming you're running that low of power chances are you should have a cel

    Alright, so if there's no cel light right now, the car doesn't notice this as a problem. First thing you should check now are vacuum lines, intake hoses, etc. Possible boost leak

    I don't exactly know to tell you the truth. A 16g isn't too too big and I know a lot of people run the 255 fuel pumps so I know that's what I'm going to do. You'll also want to run bigger injectors.

    There's plenty of options out there, but it's ultimately going to come down to what your plans are for mods.
    If you have a good local tuner around, stop by or give them a call. Especially since you're going to need a pro tune for a bigger turbo and fuel pump

    Following up on my own post....If you do not know the exact problem, have it towed to avoid any risk of further damage.
