To begin, remove the air cleaner assembly and verify that the
Accelerator Cable, cruise control cable (if equipped), and throttle valve operate smoothly without binding or sticking. Inspect the throttle bore, throttle valve, IAC by-pass port, and canister purge vacuum port for carbon deposits; if present, remove the throttle body from the vehicle and the IAC motor, then clean both with a spray-type carburetor cleaner and a toothbrush. If the throttle valve does not operate freely after cleaning, replace the throttle body. Disconnect the negative battery cable from the ground stud on the left shock tower, then remove the air cleaner assembly. Disconnect the canister purge vacuum hose from the throttle body and detach the accelerator cable and cruise control cable (if equipped) from the throttle valve lever. For four-cylinder engines, remove the accelerator and cruise control cable bracket and position it out of the way. Disconnect the TPS and IAC sensor connectors from the throttle body, remove the mounting bolts, and withdraw the throttle body and gasket from the manifold. The throttle body O-ring seal on 2.0L four-cylinder engines is reusable; inspect it for hardness and cracks, and if no defects are found, it may be reused. For all other models, remove all traces of gasket material from the throttle body and manifold, and clean the throttle body if necessary. Install the throttle body with a new gasket (reuse the O-ring seal for 2.0L four-cylinder engines) onto the intake manifold, then tighten the throttle body mounting bolts to the specified torque. Complete the remaining installation steps in reverse order and ensure that the throttle body operates freely after installation.
