my truck is running rough i took it to auto zone to have it checked out.The code i got back is PO316 what does this mean please i need help thank you for any help.

 

My research on that code says it's a miss fire. How many miles are on your truck and which engine do you have? Might be time for some new plugs\wires\COP's.

 

my 2002 fx-4 has a 5.4 v-8 the mileage is 96000 . thank you for all your help.

 

Yup - PO316 means misfire in the first 1,000 rpms. Definitely time for some new plugs\wires\COP's if they are original with that many miles.

 

No wires on that one, you have Fords High Tech COP ignition system lol, -get your coils from Global Auto = ebay.

 

I WOULD APPRECIATE THE PART NUMBER for the cops for my 5.4 engine.i seen them on e-bay but dont know the part number.any help would be appreciated. Thank you 2002 FX-4 96000 MILES
