Remove the three nuts that hold on a plastic
cover, and this will expose coils 4, 5, 6.

• Coil for cylinder 4 plug is below.
• Coil for cylinder 5 plug is below.
• Coil for cylinder 6 plug is below.

• Remove three bolts holding the throttle cables
• Move the throttle cables out of the way,
  temporarily attaching to the latch that holds the
  hood support.

Driver

• Remove the PCV valve. Hold down on black ring
  against the manifold, and it will slip off
  easily.
• Loosen clamp and separate air intake.
• Disconnect two (2) electrical connections - I
  believe these are the Idle Air Temperature (IAT)
  sensor (3a) and the Throttle Position Sensor
  (TPS) (3b).
• Remove two bolts so that unit separates from
  manifold. Note that there is a metal gasket
  between this unit the manifold take care not
  to lose it or have it fall.

• Remove electrical connector.
• Remove two bolts and then remove unit from
  manifold.
• Reach behind the manifold to find a bolt that
  holds on this tube. Remove the bolt, and be
  careful not to lose the bracket (it may fall off
  the hose).

• Referencing the smaller picture, you will notice
  a connector on the back of the manifold that
  holds a rubber tube. You will need to reach
  behind the manifold to remove this tube, but it
  slips off easily with no tools.
• Below the smaller tube (1), there is also a
  larger tube used for drainage. Trace this tube
  around the back (2a) and under the air intake.
  You will find it easier to disconnect this tube
  at this position (2b).

Driver

• Remove bolt (bracket to manifold) from passenger
  side of manifold.
• Remove bolt (bracket to manifold) from rear you
  will need to reach behind the manifold and feel
  for this bolt. It is beside the bracket bolt in
  that was removed previously.
• Remove bolt (bracket to manifold) from driver
  side of manifold.
• Move this tube from on top of the manifold to the
  side of the manifold.

• Remove six (6) manifold bolts.

• At this point, the manifold is loose, and you can
  begin to move it out and away in a
  counter-clockwise direction so as to expose the
  1-2-3 plugs coils. As you begin to move it,
  you may notice that this hose near the air intake
  (driver side of the engine) will get in the way
  (I think this is the EGR valve). Disconnect it
  and you should be able to complete moving the
  manifold.

Now that the manifold is moved, the 1,2, 3
coils are exposed.

• Coil for cylinder 1 plug is below.
• Coil for cylinder 2 plug is below.
• Coil for cylinder 3 plug is below.
