My fight with P 0171 continues -an advice desperately sought

with occasional P 0445 assisting... I thought that to address "a massive leak" in the evaporative system would be easier than to chase elusive P0170. I did not find any broken hose connecting canisters. but I did not succeed in removing the purge valve. Two molded tubes are connecting it to steel tubes by the some strange contraption that refused to cooperate. I was squeezing it, pushing, pulling and twisting, but in vain. Do I need some special tool to do it?
I finally got more sofisticated data reader than just a plain code reader.
Live data not encouraging : shortFT1 -3.1
shortFT2 -3.9
long FT1 19.5
longFT 2 0.6
at idle speed.
at 2000RPM sFT1 15.6
sFT2 -2.3
lFT1 10.9
lFT2 5.5
it seems to indicate the right bank has an air leak, but I cannot find it. Spraying carb cleaner around manifold did not change idle speed. The motor runs smoothly, accelerates ok, but as I stated previously every once a while it goes to "restricted performance" mode for a few minutes before recovering to its normal regime. Any advice appreciated. I am out of my wits.
