2002 Ford Taurus SES P0316 Fault: Diagnosis and Solutions

Model: 2002 Ford Taurus SES Fault Code: P0316 Posted: 2016-02-06 19:41

Hi everyone, I'm having trouble with my 2002 Ford Taurus SES that's showing fault code P0316. I've already replaced the spark plugs, plug wires, and coil pack—all from Motorcraft. A fuel pressure test came back normal, and a vacuum check revealed slight late timing. The car stumbles and surges at idle and during acceleration. No other diagnostic codes are present. Any insights or troubleshooting steps would be greatly appreciated! Thanks for your help.

Were there any additional fault codes? What was the exact fuel pressure reading? Perform a fuel pressure leak-down test with the engine off (KOEO). Also, consider cleaning the Mass Airflow Sensor (MAF) and please share your results for these checks.
