Your next step is to check the compression and fuel. You could have low compression or a bad fuel injector or a Burnt valve

HI......
OK. just follow the number on the ignition coils.
And the number on the cylinders are.
The FIREWALL side are 1,3,5, Starting from the belts location.
The RADIATOR side are 2,4,6, Starting from the belts location.
The coil with number 1 go to cylinder 1. as the same way the rest of the coils and cylinders.

OK... I hope this solve your question .

THank you for use fixya.

Ok since you did all that if you want to swap around fuel injectors taking note where you put cylinder 1 injector. Lets say you swapped it with cylinder 4 . Now if you get a different code say P0304 which is for cylinder 4 misfire then you know it is your injector at fault. These are wear items and should be replaced every 100,000 miles.
Also i would suggest if you dont want to do that is get some good high octane gas when you are completely empty and fill to 1/4 tank now put in Lucas Oil fuel injector cleaner and run the car till empty. Now fill up tank with high octane gas in see if this helps. Clear code after your second tank of gas and see if the code comes back. if code does pop back up then i would do the swapping of injectors as i stated earlier. I hope this helps and good luck with the diagnosis.

    Spark plugs


    Check this SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

    1_23_2012_5_10_32_pm.jpg

    1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
    Packs off and precede with step 2 from here.
    2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
    when using compressed air, as flying dirt particles may cause eye injury. NOTE:
    Clean the spark plug recess area before removing the spark plug. Failure to do so could
    result in engine damage because of dirt or foreign material entering the cylinder head, or
    by the contamination of the cylinder head threads. The contaminated threads may prevent
    the proper seating of the new plug. Use a thread chaser to clean the threads of any
    contamination.
    3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
    removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
    cause the plug threads to seize, causing damage to cylinder head threads.
    4. Inspect the spark plugs.

    INSTALLATION PROCEDURE

    1_23_2012_5_11_30_pm.jpg

    1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
    to the gap specifications. NOTE:
    • Use only the spark plugs specified for use in the vehicle. Do not install spark
    plugs that are either hotter or colder than those specified for the vehicle. Installing
    spark plugs of another type can severely damage the engine.
    • Check the gap of all new and reconditioned spark plugs before installation. The
    pre-set gaps may have changed during handling. Use a round feeler gage to ensure
    an accurate check. Installing the spark plugs with the wrong gap can cause poor
    engine performance and may even damage the engine.
    2. Install the spark plugs to the cylinder head. NOTE:
    • Be sure that the spark plug threads smoothly into the cylinder head and the spark
    plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
    cylinder head. Cross-threading or failing to fully seat the spark plug can cause
    overheating of the plug, exhaust blow-by, or thread damage.
    • Refer to Component Fastener Tightening Notice in Service Precautions.
    Tighten the spark plugs to 18 N.m (13 lb ft).
    3. Install the ignition coils.

    How do you change spark plugs in a 2004 hyundia sonata


    It depends on which engine is in the vehicle. The 2004 Sonata came with two possible powertrains -- the 2.4 Lit L4, and the 2.7 Lit V6.

    On the 4 cylinder engine, there are two coil packs and two ignition wires, Below each coil pack is a spark plug (#2 and #4 cylinders). The wire from # 2 coil pack goes to #3 spark plug, and the wire from #4 coil pack goes to #1 spark plug.

    Photo:

    ghost45_15.jpg
    Now the 2.7 Lit V6 requires you remove the surge tank (intake manifold) in order to access the spark plugs & wires on Bank 1 (Right Hand side of the engine).

    Firing Order diagram for 2006 Ford Explorer


    Hope this helps. The ignition coil:
    • changes low-voltage pulses from the PCM to high-voltage pulses.
    • fires 2 spark plugs simultaneously.
    • has 3 transformers.
      • One transformer fires the spark plugs for cylinders 1 and 5
      • One transformer fires the spark plugs for cylinders 2 and 6
      • One transformer fires the spark plugs for cylinders 3 and 4
    Spark plug wires:
    • carry high-voltage pulses from the ignition coil to the spark plugs.
    The spark plugs:
    • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
    The firing order is 1-4-2-5-3-6.

    3. Misfiring at the #1 on the Distributor/Electronic Iginition Coil.

    a. Unplug the #1 Wire at the #1 on the Distributor/Electronic Ignition Coil.
    b. Using an Auto electrical testing: Probe, wire and ground clip electrical, stick the Probe into the opening at the #1 Distributor/Electronic Ignition Coil. Use the grounding clip - clipped to a portion on the engine.
    c. Start the Vehicle and check for rhythmic spark.
    d. If there is NOT rhythmic spark, the Distributor/Electronic Ignition Coil needs to be replaced.
    e. Turn off the engine.
    f. If there is rhythmic spark: Reconnect the #1 Wire at #1 on the Distrubutor/Electronic Igntion Coil.
    g. Disconnect the #1 Wire from the #1 Spark Plug.
    h. Again using an Auto electrical testing: Probe, wire and ground clip. Insert the Probe into the end of the #1 Wire and clip the ground clip onto the engine.
    i. Start the engine again.
    j. Again Check for rhythmic spark.
    k. If there is NOT rhythmic spark the #1 Wire needs to be replaced. (Replace all Wires as a Set).
    l. If there is rhythmic spark then the #1 Wire is fine.
    m. Turn off the engine,
    n. Remove and Inspect the #1 Spark Plug. Clean if necessary and Regap.
    o. Reinstall the Spark Plug and reconnect the #1 Wire.
    p. Restart the engine.

    Timing the cams and crank with a belt


    1. Note: Electronic Ignition engine timing is entirely controlled by the PCM. Electronic Ignition engine timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings.

    The CKP sensor is used to indicate crankshaft position and speed by sensing a missing tooth on a pulse wheel mounted to the crankshaft. The CMP sensor is used by the COP Integrated EI System to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.
    1. The PCM uses the CKP signal to calculate a spark target and then fires the coil pack(s) to that target shown in Figure 51. The PCM uses the CMP sensor not shown in Figure 51 on COP Integrated EI Systems to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.
    1. The coils and coil packs receive their signal from the PCM to fire at a calculated spark target. Each coil within the pack fires two spark plugs at the same time. The plugs are paired so that as one fires during the compression stroke the other fires during the exhaust stroke. The next time the coil is fired the situation is reversed. The COP system fires only one spark plug per coil and only on the compression stroke.

      The PCM acts as an electronic switch to ground in the coil primary circuit. When the switch is closed, battery positive voltage (B+) applied to the coil primary circuit builds a magnetic field around the primary coil. When the switch opens, the power is interrupted and the primary field collapses inducing the high voltage in the secondary coil windings and the spark plug is fired. A kickback voltage spike occurs when the primary field collapses. The PCM uses this voltage spike to generate an Ignition Diagnostic Monitor (IDM) signal. IDM communicates information by pulsewidth modulation in the PCM.
    1. The PCM processes the CKP signal and uses it to drive the tachometer as the Clean Tach Out (CTO) signal.

    2.5L V6

    The ignition system consists of an ignition coil, spark plug wires and spark plugs.
    The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by a pulse former within the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
    Ignition timing is determined by the powertrain control module in response to engine operating conditions based on stored data tables or maps. Once ignition timing has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
    The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 5, cylinders 4 and 3 and cylinders 2 and 6) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This ensures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

    Integrated Electronic Ignition System The Integrated Electronic Ignition (EI) System consists of a crankshaft position (CKP) sensor, coil pack(s), connecting wiring, and PCM. The Coil On Plug (COP) Integrated EI System uses a separate coil for each spark plug and each coil is mounted directly onto the plug. The COP Integrated EI System eliminates the need for spark plug wires but does require input from the camshaft position (CMP) sensor.
