PO446 and PO440
PO446 and PO440
I have a 2003 Pontiac Vibe with 299,672 miles on her. CEl light came on recently, had it checked at the local parts store and the scanner came back with two codes: PO440 and PO446. When the vehicle sits for more than a few hours and I start it up, I get a whiff of gas that comes through the vents. I have already replaced both the purge valve and vent vale, any other thoughts on what to look at next?
