Can somebody post the directions on how to take the intake manifold off? Specifically, I need to take the intake manifold off the head so I can replace the head gasket. FSM is very vague: "remove 2 intake manifold braces and remove intake manifold". However, I can't get to the lower bolts holding the manifold to the head.

From the Haynes Repair Manual:

5 Intake manifold - removal and installation

1-6: Removal
7-13: Installation

  1. Relieve the fuel system pressure (see Chapter 4). Disconnect the cable from the negative battery terminal.
  2. Drain the cooling system (see Chapter 1).
  3. Label and detach all wire harnesses, control cables, cooland and vacuum hoses connected to the intake manifold.

  4. Remove the fuel rail and injectors (see Chapter 4).
  5. Unbolt the intake manifold from the two braces from underneath the vehicle. Some models may only have one brace, a tubular strut connecting the intake manifold to the power steering bracket.

    There is also a bracket connected to the throttle body and bolted to the rear of the block (see Chapter 4, Section 13).
  6. Remove the mounting nuts/bolts, then detach the manifold from the engine.

    Note: The intake manifold is a two-piece design, with a plenum located below the manifold. It is possible to remove the plenum with the intake manifold mounted to the engine, but the bolts are difficult to reach with a wrench. It is easier to remove the intake manifold and plenum as a unit.
  7. Use a scraper to remove all traces of old gasket material and sealant from the manifold and cylinder head, then clean the mating surfaces with lacquer thinner or acetone.
  8. Install a new gasket, then position the manifold on the cylinder head and install the nuts/bolts.
  9. Tighten the nuts/bolts in three or four equal steps to the torque listed in this Chapter's Specifications.

    Follow the tightening sequence.

  10. Install the remaining parts in the reverse order of removal. Refill the cooling system (see Chapter 1).
  11. Before starting the engine, check the throttle linkage for smooth operation.
  12. Run the engine and check for coolant and vacuum leaks.
  13. Road test the vehicle and check for proper operation of all accessories.
