Code 316 means the engine computer has detected a miss-fire on startup. You normally get a code for the cylinder causing the problem.
If the spark plugs are original, I would start with checking them for signs of damage or excessive wear.

I would check for moisture/water on or near the PCM. Here is a youtube video to show you how to check: Ford Freestar Rough Idle and other Electrical Issues DIY

Code 316 is an extension of your Code 304. 316 means its misfiring in the first 1000 RPM's and 304 means number 4 cylinder is the problem cylinder.
Could be a bad wire, coil, or sparkplug.

These codes are making me lean towards the ignition coil pack.My stepson's 2001 Sable 3.0 v6 had one cylinder misfiring(5-code P0305),which shares a coil with cylinder 1(code P0301).I diagnosed it by trading wire 1 and 5 at the coil,and the code changed to P0301.You have codes for the two cylinders on the same coil,so this is most likely it.(these codes would also trigger P0300(Multiple Misfires Detected) and P0316(Misfire Detected First 1000 Revs)).

Hi,

Are you are referring to Fault Code P0316?

If yes, then P0316 = Misfire Detected On Startup (First 1000 Revolutions)

This is a generic code for all vehicle makes and as this code has not identified a particular ignition circuit, further diagnostic analysis will be required to determine the cause of the initial misfire.

If this misfire condition does not re-occur, your OBD computer will eventually erase this code.


Hope this helps.......

P0316 means that there was a misfire within the first 1,000 engine revolutions.

p0172 Basically this means that an oxygen sensor in bank 1 detected a rich condition

p0316 crankshaft position sensor

clean your intake and check you cap / rotor

Code - P0316

Misfire detected on start up
first 1,000 revolutions.

Code P0316 means 'misfire detected first 1000 revs.'
