REMOVAL & INSTALLATION
See Figures 1, 2 and 3
The following procedure can be used on all years and models. Slight variations may occur due to extra connections, etc., but the basic procedure remains the same.
- Disconnect the negative battery cable.
- Remove the nuts attaching the air cleaner adaptor to the throttle body, loosen the hose clamps, and remove the air cleaner adaptor.
- Remove the three control cables-accelerator, automatic transaxle kickdown (if equipped) and cruise control (if equipped) cables. Then remove the throttle cable bracket from the throttle body.
- Label, then disengage all wiring harness connectors and vacuum hoses from the throttle body.
- Remove the throttle body-to-intake manifold retaining nuts, then remove the throttle body and its gasket.
- Clean the gasket surfaces and install a new gasket. Install the throttle body-to-intake manifold retaining nuts and tighten them alternately and evenly to 15 ft. lbs. (20 Nm).
- Reattach all vacuum hoses and wiring harness connectors, checking that their routing is correct and that their connections are secure.
- Install the throttle body cable bracket. Tighten the retaining nuts until secure.
- Attach all of the applicable throttle body cables (accelerator, transaxle kickdown and cruise control).
- Install the air cleaner adaptor and air inlet hose to the throttle body.
- Connect the negative battery cable.
- Road test the vehicle for proper operation.
The MFI system idle speed adjustment is the same as the EFI system adjustment; refer to the throttle body procedure under the Chrysler EFI system instructions earlier in this section.Idle Mixture
The air/fuel mixture on all fuel-injected cars covered by this information is automatically controlled by the Powertrain Control Module (PCM). The mixture is not adjustable, nor does it require routine adjusting.
