so are you trying to tell me theres a hole in a hose somewhere?

 

Yes I would check for a leak and also check the O2 sensor.

 

any good starting places? umm would this be cause by a leak on the first pipe right off of the turbo before it goes into that metal cross pipe that runs along the front of the car?

 

what your code means is that your engine is either getting too much unmetered air or it is unable to supply the needed amount of fuel. odds are that it is letting in too much air. most common culprits are maf sensor or vacuum leak or check any air lines from after the airbox.

 

alright then. ill get on it. thanks guys. anyone have like a diagram off all the hoses and pipes and stuff. it would probably be on the one that i would never see.
