I did a fuel pressure test 57psi engine running and off.
Ran live data and noticed the upstream o2 sensor running at .050 to .075 when it was running the worst then it varied between .95 and .05 when it smoothed out.this is every start(swapped out the o2). But no still no cel or pending codes.last week I did the full seafoam treatment ,cleaned the iac,and maf after changing the timing belt and recently changed plugs and wires.

I read your posts. I am not sure what your issue is? That might be why no one responded. Do you have codes now?
One thing you do with the lean code is change the airfilter, check intake for blockage and remove and clean the MAF.
