Expert:  Eric replied 6 years ago.

Hi,

The reason for the high cost or replacing the plugs is because the intake manifold has to be removed in order to access all the plugs.

this all should be in your manual, but i am putting it together in one location:

Intake removal:

REMOVAL
1.Remove the air intake hose connected to the throttle body.

2.Remove the accelerator and cruise control cables.
3.Remove the engine coolant hose and throttle body.
4.Remove the P.C.V. hose and brake booster vacuum hoses.
5.Disconnect the vacuum hose connections.

6.Remove the surge tank stay.

7.Bleed off the pressure in the fuel pipe line to prevent the fuel from spilling.
8.Disconnect the connector from high pressure hose.

9.Remove the surge tank and gasket.

10.Disconnect the fuel injector harness connector.

11.Remove the delivery pipe with the fuel injector and the pressure regulator.
When the delivery pipe is removed, be careful not to drop an injector.

12.Disconnect the wiring harness of the coolant sensor assembly.
13.Remove the surge tank.

 

Ignition coils and ignition wires:

  • disconnect ignition coil harness connectors
  • disconnect ignition wires from ignition coils
  • remove hold down bolts from ignition coils
  • while gently twisting pull up and remove ignition coils
  • while gently twisting pull up and remove ignition wires
  • remove spark plugs
  • Install in reverse order
