found hairline crack on pcv hose
like the title, i kept getting a po171 and 174, figures it was the granatelli maf, then the code started to come on more an more, almost killing my top end power, really frustrating, so i figures id take a look at the obvious, just at a glance i never saw anything, then i became more persistent, turned the hose around and found the crack on the hose going to the intake right behind the tb.
fixed the vacuum leak and codes are now gone, and no more lack of power intermittently.
i just made this thread as to let everyone know, there is some alerts on it in the gm system, so just giving ya guys a heads up
