Message:
2001 DODGE DAKOTA 4.7. DRIVING HOME STARTED TO RUN
REALLY ROUGH AND EXHAUST POPPING CHECKED THE CODES AND
NEEDED AN O2 SENSOR AND POWER STEERING PRESSURE SENSOR. I
ORDERED THE STUFF THINKING THE O2 SENSOR WAS CAUSING THE
PROBLEM REPLACED AND RESET THE COMPUTER ABSOLUTELY NO
DIFFERENCE STILL ISNT RIGHT. POWER SEEMS TO BE NORMAL IDLING
IS ROUGH RPMS DROP TO 500 OR SO AND THE EXHAUST IS POPPY
JUST IDLING AND SAME RESULT WHEN CRUISING AT STEADY SPEED.
HAVE NOT GOT ANOTHER CEL SINCE COMPUTER RESET. SORRY FOR
THE NOVEL BUT ANY IDEAS????

Change the power steering pressure switch and clean the
wiring harness and connectors to the O2 sensor. Chances are
the O2 sensor never was the problem. It's something that's
been discussed on here several times before.

Daddio is right, as it happened to my 2000 4.7 liter several years ago.
The power steering high pressure switch leaks fluid into the wiring harness, fouling the drivers side pre cat O2 sensor.
Replace the switch, clean up the O2 sensor and wiring, add PS fluid if needed, you hopefully will be good to go.
