Sorry posted wrong year! It's a 2013 !!

I was having an intermittent "Check Engine" light showing P0171. Connected my diagnostic tool and found very high (38+) LTFT at idle that would slowly decrease at higher RPM to (25). Started by checking for vacuum leaks and this is what I found. PVC hoses cracked and brittle (see pictures). Temp fix with duct tape while waiting for a new replacement from AC Delco. Better already with less fuel consumption! Hope this helps others.

I voted once for my 176K STS. How do I register a vote for my 86K STS??

'93 STS w/176K and still running strong without timeserts !!
