If this is correct, look for vacuum leaks.
Start with the L shaped formed hose on the back and side of the intake
manifold. Then check the Y shaped hose in back of the intake manifold.
Good luck

 

check the vacum hose cloestest to you on the intake manifold i got that code once and i found that vacum hose had a ripe in it i replaced it and reset the code and i never came back

ok, ill check the hoses today. we are talking about the hose that goes right into the intake right? should i take my engine cover off to see any other hoses?
thanks

 

yes

 

holy cow there are a ton of hoses...

the hose coming from the intercooler to th intake seems to be fine, as do the little ones going into the back.

anything else i should check?

is the maf right on top of he air filter housing?

 

Check the L shaped hose between the G-12 reservoir and the intake manifold.
Look for cracks in the elbow. Then check the Y shaped one in back of the
intake manifold. Squeeze the hoses.

System too Lean 2)

- Check intake air system for leaks ("false air") Page 24-97 Check vacuum hoses for leaks. listen for hissing. Yes, take the engine cover off so you can see the hoses. The thin vacuum hoses crack easily.


- Check Mass Air Flow (MAF) sensor -G70- Page 24-57


- Check fuel pressure regulator and residual fuel pressure Page 24-93

- Check fuel injectors Page 24-87
- Output Diagnostic Test Mode (DTM) Page 01-42

Most likely the first or second. Most likely vacuum leak from a cracked vacuum hose. Second most likely is is the MAF.

 

the little hose in the front of the intake was completely shot, i'm going to replace it and see if that helps. would that effect fuel mileage?

 

Yes, the fuel injectors compensate for the lean condition by injecting more fuel.
