1996 Plymouth Voyager

Engine Performance problem
1996 Plymouth Voyager 6 cyl Two Wheel Drive Automatic

I have a 1996 plymouth voyager, I have replaced all sensor and the code keeps coming up as a co2 sensor, I had the transmission replaced and then it start running for 60 miles then it is like sucking in air and will back fire and turn off, then u wait a couple of days and it will crank and runn fine for 60 miles and do it again any advise before I send it to the scrap yard tired of messing with it
thanks from North Carolina

Codes coming back !
PCM not reading the correct info back from the sensor and that could be due to wiring
and have to do an ohm testing on the wiring between sensors and PCM
check fuel pressure
check for vacuum leaks
what do u have for codes
