2001 nissan sentra code po171

I have a 2001 nissan sentra gxe 1.8L. It has a lean code 171. it is runing with a missfire and it has no power when pressing the acclrater.
it seems like MAF senser.
I have replace MAF no diffrence and I replace the fuel filter in side the tank, it was very durty but still no diffrance.
All of my O2 senser are reading lean so I am thinking it is feul problem but my fuel presser seems good 35psi and 45 psi with vacume off the fuel regulater.
now I am thinking it might be the PCM.........
PLEASE HELP ME OUT.

Ok the fuel pressure is very good , and you replace maf sensor too,
i think 2 probable throubles, one , the catalyc converter clogged , to check remove exhaust pipe section before catalyc and run engine, its very loudness, other is tps fault, tps is throttle position sensor, located on acceleration body

Nissan Sentra 2001 gxe with code p0420


You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.
