I have a 2001 GMC Yukon with a 5.3 engine(T). I have been having problems with 1. the ASPIRATOR which is located above the drivers head in the headliner. It seems to maybe have some problems with the fan sounding to load.
2. My check engine light comes on and when I check it with my OBII tesster the code comes back p0466? any help on these two questions would be a big help. thanky you in advance for your time and help.
