    MAF is shot. Loss of boost is likely the car going into "limp mode".

    [EDIT] It's fine to drive, you'll just use more gas and your traction control is indeed off. No way to turn it back on that I'm aware of without fixing the problem first.

    ^^ Yup, It's the sensor that's plugged into the round plastic bit between your intake and the turbo inlet pipe.

    Buy it on-line in Canadian funds. You'll have it in a couple of days:

    http://www.autopartsway.ca/autoparts....8%20L4~240551

    Or if you're really hurting, go to the dealership and pay probably $200+.

    Well, I'd suggest getting the car scanned first to make sure that's the problem 100%. I bought my replacement OEM one from autopartsway.ca last year. I think it was around $112.

    [EDIT] RIC, FAAAAST!

    Replacing it is EASY as they give you the MAF and the surround that it plugs into. Loosen the host clamps on both sides of the original MAF, unplug the harness, swap.

    Ya man... I agree with Roland. Get the car scanned if you can, to make sure that that is the problem. I'd scan it for you for $20 . Actually I'll do it for free if you're in Mississauga

    Nah man... I won't charge you to get your car scanned. It was an inside joke. If you're in Milton tomorrow you can meet me somewhere close to my place (Derry & Winston Churchill) after 5 pm and I'll scan it for you.

    [EDIT] Something else you might want to try is to pull out your MAF, place it in a ZIP Lock bag with some rubbing alcohol and swoosh it around. Then let it air dry and install it. I've heard some people were successful with that method. I wasn't though

    BTW, you can take the MAF out by undoing the clamps for the hoses instead of taking it out with the weird screw driver. That's what I do.
