hey guys and girls

for some time now i been having some pretty weird fuels issues. i dont really know how to explain it but what happens is my car would be running fine with no issues then all of a sudden my afr (hijacked oil temp guage) will peg 20:1. it will stay fluctuating between like 20:1 and 18:1 for sometime 20ish seconds or so then all of a sudden it should back up to a cruising 13-15:1 and runs great again. i am full bolt on with pwm meth with procede and my dp are cattless so its hard to tell if my o2 sensor is pooched but i suspect it is. i dont think its tune related because i still get the no fuel feeling on map 0(stock map).i managed to get a log of this. i loged fuel pressure which seems to be relatively constant so i am ruling out fuel pump but my fuel trim in bank 1 tags 0 when this is happening when my fuel in back 2 is normal, which is why i suspect o2 sensors in bank 1. and as you can see form the log my afr is 20:1 when this happens.

any suggestions or opinions on this would be greatly appreciated
thanks

Or could this be an injector issue in bank 1?

Sounds like a bad wire. Check the O2 cable by the exhaust manifold where the boost solenoid vac lines run, it could be getting freyed. Is it throwing any codes?
