In order to change the rear plugs without the benifit of a lift, you will need to remove the upper intake manifold:
Upper intake manifold:
- Disconnect the negative battery cable. On Sebring convertible, Cirrus, Stratus and Breeze models, disconnect the negative battery cable from the left strut tower. The ground cable is equipped with an insulator grommet, which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
- Properly relieve the fuel system pressure using the procedure outlined in .
CAUTION Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure MUST be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
- Disconnect the fuel line(s) from the fuel rail assembly. On quick-connect fittings, squeeze the fitting retainer tabs together and separate the connection.
CAUTION Wrap shop towels around the connection to catch any gasoline spillage.
- Loosen the throttle body air inlet hose clamp, then release the snaps holding the air cleaner housing cover to the housing. Remove the air cleaner cover and inlet hose from the engine.
- Unplug the vacuum connection at the power brake booster and the PCV valve. Disconnect all remaining vacuum hoses and pipes, as necessary. Tag for identification, if necessary, to save time at assembly.
It may be helpful to identify and tag each sensor connector and vacuum connection as it is being removed or disengaged. This may save time at assembly.
- Disengage the connectors from the Manifold Absolute Pressure (MAP) sensor and the intake air temperature sensors.
- If necessary, disengage the power steering pressure switch and oxygen sensor connectors.

- Remove the plenum support bracket located to the rear of the MAP sensor.
- On all models except Sebring and Avenger coupes, loosen the attaching bolt, then remove the air inlet resonator. This is located on top of the engine intake manifold plenum.
- On Sebring and Avenger coupes, remove the control wiring harness mounting fasteners located on top of the upper plenum near the valve cover.
- Disconnect the Throttle Position Sensor (TPS) and the Idle Air Control (IAC) motor electrical connections.
- Remove the throttle body assembly as outlined in .
- Remove the throttle cable bracket.
- Remove the EGR tube from the engine intake manifold.
- On Sebring and Avenger coupes, remove the EGR valve and transducer assembly.

- Remove the plenum support bracket located to the rear of the EGR tube.
- Remove the 7 bolts attaching the upper intake plenum to the lower manifold, and remove the plenum.
The distributor cap is accessible by removing the air intake tube from the aircleaner to the throttle body:
- Disconnect the negative battery cable. On vehicles other than Sebring coupe or Avenger, there is a remote connection at the left strut tower, which is equipped with an insulator grommet; be sure to place this grommet on the stud to prevent the negative battery cable from accidentally grounding.
- If necessary for access, perform the following:
- Remove the bolt attaching the air inlet resonator to the intake manifold.
- Loosen the clamps holding the air cleaner cover to the air cleaner housing.
- Remove the PCV make-up air hose from the air inlet tube.
- Loosen the hose clamp at the throttle body.
- Remove the air cleaner cover, resonator and inlet tube.
- Remove the EGR tube.
- Mark for identification, if necessary, and remove the spark plug wires from the distributor cap.
