OK - well now I am really lost. Original posts indicated a MAF sensor bad with the P0171 and P0174 codes coming up. Well, we will continue to look for leaks, I will have him check the elbow hose. The car runs great and mileage is around 16 which seems pretty good, probably could be a little better.

There is no whistle noise that I hear either. I will have him check the hoses more carefully again. Any other obvious locations for a vacuum leak he should look for??

Thanks again.
