After installing a K&N CAI, and e3's in my 06 charger r/t it is

Because revving the motor makes the oil pump spin faster and therefore increases pressure. It should be stable and within specs when you are at cruising speed.

K & N is the number one killer of mass air flow sensors the oil gets burnt onto the fine wire and takes several cleanings to remove this film and the best sensor cleaner just aint good enough for one cleaning.

Po113 is the air temp code it was not transferred from old air cleaner po102 is a air flow code set from over oiling the new filter. the engine still will never rev over 3,000 rpms due built in rev limiter to stop over reving with no load.

Google the question-Plenty to read

There are several tools for that

When you buy a brand new 5.4 3 valve,
you bring it home & remove the 2 piece
plugs & install the one piece Champion 7989

Now your years down the road & have a problem

Changed the oxygen sensors at 100,000 miles?

Trans & Power Steering Fluid on all your vehicles
every 3 years- brake fluid every 2 years

Spark Plugs get Changed every 3 years

as for the valve cover gaskets, if no oil leaks there ok. as for the plug wires, when replacing. do one wire at a time as not to get them on the wrong cylinders. dont forget to make sure gap is right on plugs before putting them in. good-day !

Inspection & Gapping

3. Disconnect the 4 ignition coil-on-plug electrical connectors.
   NOTE When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal. Remove the 4 bolts and the ignition coil-on-plugs.
   
   WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
   
   NOTE Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.
   
4. Remove the 4 spark plugs.

To install:

1. Inspect the spark plugs, as outlined in this section.
2. Adjust the spark plug gap, as necessary, to 1.25-1.35mm (0.049-0.053 in.).
   WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
   
3. Install the spark plugs and tighten to 12 Nm (9 lb-ft).
   NOTE Apply a small amount of dielectric grease to the inside of the ignition coil-on-plug boots before attaching to the spark plugs.
   
4. Install the 4 ignition coils and bolts and tighten to 10 Nm (89 lb-in).
5. Connect the 4 ignition coil electrical connectors.
6. Install the alternator air inlet duct and the 2 nuts and the bolt. Tighten to 6 Nm (53 lb-in).
7. Connect the negative battery cable.

If there is a misfire, the cylinder that it is misfiring in will be recorded as a code in the computer.

Have the car scanned to determine which cylinder is bad. Then, replace the coil pack going to that cylinder.

Ignition Coil Pack Removal & Installation 2V Engine To Remove:

1. Twist the spark plug wires off of the ignition coil towers. Mark the spark plug wire positions so they can be installed in their original positions.
2. Disconnect the electrical connector from the ignition coil. CAUTION
   When removing the spark plug wires, a slight twisting motion will break the seal and ease removal.
   
   
   
3. Remove the mounting screws and remove the ignition coil.

To Install:

1. Position the ignition coil pack on engine.
2. Install mounting screws and torque to 53 in-lbs. (6 Nm).
   
   
3. Connect ignition coil pack electrical connector.
4. Match previously marked spark plug wires to ignition coil and install.

4V Engine To Remove:

1. Remove the RH cowl grille
   
2. Remove the screws and the water shield
3. Mark spark plug wire positions
4. Disconnect the spark plug wires from the ignition coil CAUTION
   When removing the spark plug wires a slight twisting motion will break the seal and ease removal.
   
5. Disconnect the ignition coil electrical connector
   
   
6. Remove the mounting screws and remove the ignition coil

To Install:

1. Position ignition coil pack. Install mounting screws and torque to 56 in-lbs. (6Nm)
   
   
   
2. Connect ignition coil pack electrical connector
3. Match previously marked spark plug wires to ignition coil and install
4. Position water shield and install screws
5. Install RH cowl panel

Hi: I would use the NGK Plugs Myself:
Spark Plug is a NGK-Laser-Platinum
(NGK PART # 4997) You Know Theres 2 Plugs Per Hole. I Think you'll Be Very Saisfied with These Plugs.

Spark Plug Wires - Removal & Installation

3.5L Engine

1. Before servicing the vehicle, refer to the Precautions Section.
   NOTE Twist the spark plug boot one-half turn in order to release the boot. Pull on the spark plug boot only. Do not pull on the spark plug wire or the wire could be damaged.
2. Remove the intake manifold cover, if required.
3. Disconnect the left side spark plug wires from the spark plugs.
4. Disconnect the left side spark plug wires from the ignition coil.
5. Remove the spark plug wire clips from the Manifold Absolute Pressure (MAP) sensor bracket and the heater inlet and outlet pipe tab.
6. Remove the spark plug wire assembly.
7. If replacing only one plug wire, open the retaining clips and remove the appropriate spark plug wire.
8. Disconnect the right side spark plug wires from the spark plugs.
9. Disconnect the right side spark plugs from the ignition coils.
10. Remove the spark plug wire assembly.
11. If replacing only one plug wire, open the retaining clip and remove the appropriate spark plug wire.

To install:

1. Install the spark plug wire assembly.
2. Connect the right side spark plugs to the ignition coils.
3. Connect the right side spark plug wires to the spark plugs.
4. If replacing only one plug wire, open the retaining clip and install the appropriate spark plug wire.

I really hope help you with this (remember rated this help) Good luck.

In my experience with the 2.7L engine, the spark plugs are located on the top of the engine below the individual ignition coils. The coils are placed between the intake manifold and the valve covers, 3 per side. The coils are held in with "torx" screws. Simply remove the screws, and disconnect the connectors to remove the coils. The spark plugs will be underneath. Be sure to properly gap the spark plugs for maximum life and emissions compliance. Also, an improperly gapped plug can shorten the life of the coil packs.
Hope this helps!
