HOW DO I CORRECT P0320 CODE

1996 Ford Bronco • 234,000 miles

I have replaced icm, tps, cpk, alternator, cap rotor, charged and tested battery, coil replaced, replaced both up stream 02 sensors it starts and runs for awhile then it stalls and throws a p0320 code. Once it stalls wont start again till after it sits fuel pump whistles and when you remove gas cap sounds like its blowing air or hissing sound. Dont know what to check next?

Which engine do you have?

DTC P0320: Continuous memory DTC P0320 indicates two successive
erratic Profile Ignition Pickup (PIP) pulses occurred resulting in a possible
engine miss or stall. Possible Cause: Low battery voltage.

Loose wires/connectors.

Open/Shorted circuits.

Damaged distributor cap, rotor, plugs or plug wires.

Damaged coil, ICM or PCM.

I have 351 motor Battery was tested and charged, replaced ICM, replaced coil, Replaced alternator, replaced Cap and Rotor, Will run for awhile then acts like running out of gas. It also hesitates when you reve the motor. The check engine light comes on then stalls. Code reader says p0320.

Guess you would need to plug in a scan tool to monitor the various components as listed above to see which could be working out of specs.

You would need to drive the vehicle for some distance for the monitors to be ready. Try driving on highway for 20 minutes and then back to city driving for another 1 minutes, Go back to highway for another 10 to 20 minutes and recheck if they are ready. While driving aviod sudden/abrupt accelerations.
