2004 ford taurus 3.0 dohc missing ecm codes po351 po352 po354 replaced coils and plugs all new gaskets checked all hoses no leakes.

Do you know for a fact cylinders one two and four are firing ?
The codes are for circuit problems with the coils on those cylinders. The coils get power from the PCM power relay and the engine computer grounds each coil to fire the spark plug. The codes mean the coils are not firing, and since you replaced the coils there may be too much resistance in the circuits coming from the computer.

Po351 po352 po353 po354 po355 po356

Misfire P0351,P0352,P0353,P0354,P0355, P0356 Meaning secondary circuit A,B,C,D,E,F . You may need a PCM If your car has a NGC controller it may have melted the ignition coil mounted on the spark plug. For these to happen You have a defective coil driver circuit in the PCM . This is a multiple coil failure, Before we go there lets do the basic are the connector connected? How about the conection at the juction area all connected, then pcm failed. These are secondary what is the secondary the signal that allows the coil to collapse the magnetic field and gives spark.

Hi, do you have the 4.7 liter engine with coils on every cylinder? 351 and 355 indicate bad coils on cylinders 1 and 5. You can try moving the coils to see if the problem is the coils themselves or the wiring. If the codes change after moving the coils, replace the coils. These misfires could be the cause of the other codes.

My Lincoln LS 2004 has the Check engine light on and the scan shows 3 problems: P0306, P0351 and P316, do you think these problems can be solved with a mayor tune up?

There is no such thing as a major tune-up

PO306--could be COP Ignition Coil #6 misfiring

PO316--is a misfire on first 1000 revolutions.
You always get that,disregard

PO351--doesn't apply to the LS,disregard also

I have a code po354 on my 99 expedition, book says cylinder d misfire, which cylinder is this?

I just worked on 98 expedition 5.4l had code PO354. This code refer to an open primary coil winding, open wire, or bad PCM.
Check primary winding with ohm meter should be from 0.5 to 1.5 ohms and about 2.5 ohms with a hot engine. check wiring with a noid light, run the engine and shake the harness if light goes out repair harness you should have battery voltage with key on the computer controls the ground side.
