Is it possible to be in permanent limp mode? I don't know if the air flow sensor is bad or if it's just limp mode.

See the MAF FAQ and limp mode FAQ at the top of the forum or in 1000q. I think you could be in permanent limp mode but try the most common solutions first to check the MAF.

Low power could also be a clogged fuel filter. Generally, the onset of limp mode is the power cutting out when you request more power and turning on/off the ignition resets it.

Thanks, those are very helpful I was wondering if it could also be the turbo

IMHO, if you are getting limp mode you'll feel it. It's like the engine suddenly bogs down or if you hit a really strong headwind. Accelleration is horrible with limp mode.

I would think that if there was really something wrong, you'd notice it when it was starting to get worse. Otherwise, maybe an air leak in the hoses, maybe a clogged fuel filter? You are supposed to change the fuel filter every 20,000 miles.
