I'll give you a hint. It was a vacuum leak (big surprise I know). The question now is, where was the leak at?

That's tough... The only thing I can think of, but your car is too new to have is a vacuum operated choke.

I guess the power brake booster- no wait- you said they checked the pvc valve, but i guess they missed it the first time through so I change my guess to the pcv valve vacuum hose..

So are you asking for us to guess where the leak was? Or are you wondering yourself?

Anyway did you experience anything such as a high or lopey idle? That's usually the symptoms of a vacuum leak.

They replaced all that stuff?

"A code P0171 may mean that one or more of the following has happened:

* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak downstream of the MAF sensor."

DAMN you had it Erik... should've stayed with your first guess and you would've won the prize!!!!

~~~~~~~~~~~~~~~

So, the cause was a vacuum leak .... in the hydro-booster (power brake booster) of all things. After spraying the entire engine to try and find the leak, they finally heard it near the brake booster.

So, in this whole process my car got:

- A new ScanGauge unit (and solid proof they are a great company)
- 4 brand new fuel injectors
- New O2 sensors
- New PCM
- A free cleaning of my mass air flow sensor
- And a clean engine since it was fully sprayed with carb cleaner.... lol

So to find that all you would need to do is pinch the brake booster vacuum hose?
