Might be fixed.
I had the PO171 & PO174 reading. Been looking for a vacuum leak the last couple of days. Today I tried the propane test along the vacuum lines. That did'nt turn up anything. But while I was looking for all the lines, I lifted the top radiator hose up and there was a short vacuum hose under it and it had two good size cracks in it. I taped it up really good with electrical tape for now and reset the CEL. I'll drive it around tomorrow for a while and see if that did it, then replace the hose. Wish me luck!
