Toyota Solara P1130 OBDCode

I have a 2002 Toyota Solara 2.4L 4 cylinder. (Currently:199k miles) Months
ago I got a P0420 code meaning I had a bad catalytic converter.. The code
was reset multiple times to ensure the catalytic converter was indeed bad. I
eventually changed the catalytic converter. After that, the P0130 code popped
up meaning I had a bad o2 sensor. That code was also reset. I changed the
o2 sensor.. I soon got a P0171(System Lean etc..) & P1130, I reset those
codes and the P0171 went away. But the P1130 came back.. I contacted the
company I ordered the o2 sensor from (thinking it was defective) and they
gladly sent me another sensor which I currently have installed.. but the code
persisted which is leading me to believe the problem is not the sensor but
something throwing the sensor off. The P1130 code: Air/Fuel Ratio Sensor
Circuit Range/Performance Malfunction Bank 1 Sensor 1. Now this code is
tricky because there is no definite solution just by reading the code. I changed
my spark plugs and ran some sea foam through the tank, no change. I bought
an OBD scanner to get some live data/freeze frames. First off, my car cannot
stay in Closed Loop. It either shows, OL drive/CL-Fault or just simply OL.
When it is in CL, my Short Term Fuel Trims range from -20% to +5% and my
Long Term averages -10%. The Upstream O2 sensor (B1S1) reads 3.289v in
open loop. In CL-Fault/Closed Looo: O2B1S1 ranges 3.3-3.5 which doesn't
seem ok at all. The Downstream (O2B1S2) reads just fine averaging about
0.89v. All other readings seem about right. The MAF averages 2.89 at idle and
my sparkadv averages 15(idle). Performance issues include: hesitation when
accelerating, loss of power, very bad starting problems (especially cold
starts), hard shifting between gears, very bad gas mileage, a very rough low
idle (660 average) and my car smells of gasoline.

Currently lost and looking for possible solutions. I'm thinking I have a bad coil,
a leak, bad fuel filter or bad injectors or just a defective o2 sensor.
