Throttle Body: Installation
2004 Acura 3.5RLSECTION Installation
WARNING: This page is about a different car, the 2001 Acura MDX, 2001 Acura Integra, 2001 Acura 3.5RL, 2001 Acura 3.2TL, and 2001 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.
- To install, reverse removal procedure. DO NOT adjust throttle stop screw. Start engine. Hold engine speed at 3,000 RPM until radiator fan comes on. Allow engine to idle. Hold throttle cable housing and remove slack from throttle cable.
- Turn throttle cable adjusting nut until it is 0.12" (3 mm) away from cable bracket. Tighten lock nut. Throttle cable deflection should be 0.39-0.47" (10-12 mm) when measured between throttle link and cable bracket. See Figure. If deflection is not as specified, go to next step. If deflection is as specified, go to step 4.
- Ensure throttle cable or cruise control cable (if equipped) is not binding or sticking. Loosen lock nut, and turn adjusting nut until deflection is as specified. After adjustment is completed, ensure throttle valve fully opens when accelerator pedal is pushed to floor.
- Check cruise control cable free play at output linkage. Cruise control cable is correctly adjusted when output linkage free play is 0.18-0.22" (4.5-5.5 mm) measured at cruise control cable end. See Fig 1.
- If free play is not as specified, loosen lock nut. Turn adjusting nut until engine speed starts to increase. Tighten lock nut and adjusting nut. Turn adjusting nut until it is 0.18-0.22" (4.5-5.5 mm) away from bracket. Pull cable so that adjusting nut touches bracket, and tighten lock nut. See Fig 1.
