Code p0316 Ford Taurus 3.0 l , 6cyl fuel injectied with codes of 304 , p0316 mist- fires

The P0316 DTC code is a generic code that applies to all vehicles. This code means the powertrain control module (PCM) has detected a misfire shortly after startup, specifically within the first 1,000 revolutions. This code may also be triggered with another of the other misfire codes which are P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0309, P0310, P0311, P0312. If you have another misfire trouble code also, you should diagnose and repair that code(s) first. Symptoms Symptoms of a P0316 DTC may include: MIL (Malfunction indicator lamp) illumination Rough engine start or idle Potential Causes Potential causes of this misfire code may include: Damaged or defective Crankshaft Position Sensor (CKP) CKP sensor wiring or connector fault Poor fuel quality Ran out of fuel Ignition system malfunction Fuel system malfunction: injector or fuel pump Mechanical engine problem Damaged PCM Possible Solutions First off, you'll want to repair any other misfire DTC codes if present prior to diagnosing this code. If you own a Ford vehicle and you have a P0316 along with one of the other misfire codes, you should check for appropriate TSBs (technical service bulletins), as there are some TSBs that in part involve reprogramming the PCM. Doing that requires specialized equipment. Some Ford vehicles even needed a new cylinder head as a result of the valve. Regardless, if you have a Ford with multiple misfire codes including this one, check for TSBs. If the P0316 is the only code, then it's time to do a bit more diagnosing of the crankshaft and camshaft position sensors, and their associated connectors and wiring. A tip we've found is "Since this code indicates a start up misfire, pay attention to items which may expand or contract when cold (if the code sets when the engine is cold), or hot (if the code sets on a hot restart)." Realistically, the freeze frame data from the PCM will be helpful in tracking down the problem. As will a good DVOM (digital volt-ohm meter), so you can perform tests on the wiring and the sensors.

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.

Need to get a can of gumout and with it idling spray around the top of the upper plenum to see if you have a vacuum leak if you have a leak it will either idle up slightly or kill the engine very very common on the 3.0 Taurus ,little more information would be helpful like how many miles are on the car

2002 ford taurus obd2 code B1155

The 306 is a misfire on #6 cyl

Disregard the 316

check spark plug wires and coil packs

You have a misfire on #3 for code p0303 & misfire for code p0316

po303 is cyl. #3 miss fire p0316 is random miss fire po194 is fuel pres. crkt. could be fuel pressure regulator or bad injector on #3 asuming coil has been replaced on #3

P0302 IS MISFIRE ON# 2 CYLINDER P0316 I THINK IS KNOCK SENSOR BUT IM OLNY 90% ON THAT

Code P0316 means 'misfire detected first 1000 revs.'

P0304 is Cylinder 4-misfire detected-probable cause is as follows. Engine mechanical fault, wiring, ignition/fuel system, injector, ECT/MAF sensor, ECM

P0316 Misfire detected during startup-first 1000 revolutions- probable cause is as follows-Engine mechanical fault, wiring, ignition/fuel system, injector
