CAUTION: The maximum amount by which the engine management system will adjust the camshaft timing (VCT control unit) is limited to 2 degrees. As a result of this an extremely high degree of accuracy is required for any work which affects the valve timing. NOTE: Steps which only apply to certain model variants and therefore do not apply to all vehicles are clearly marked. NOTE: The positions of the engine mountings and engine support insulators are described looking from the transaxle towards the engine. 1. Disconnect the battery ground cable. For additional information, refer to Section 414-01. 2. Loosen the front right-hand wheel nuts. 3. Raise and support the vehicle. For additional information, refer to Section 100-02. 4. Remove the front right-hand wheel. 5. Lower the vehicle. 6. Remove the air cleaner resonator and air cleaner outlet pipe. 1. Disconnect the mass air flow (MAF) sensor electrical connector. 2. Disconnect the intake air temperature (IAT) electrical sensor. 3. Remove the one bolt and two nuts. 4. Release the retaining clips. 7. Disconnect the speed control cable. 1. Disconnect the cable from throttle valve. 2. Gently move the cable up and down and pull it out of the retaining bushing. 3. Press the retaining bushing out of the bracket. 8. Disconnect the throttle cable. 1. Remove the plastic clip. 2. Unhook the cable. 9. Remove the timing belt. For additional information, refer to Timing belt in this section. 10. Remove the camshaft pulleys. 1. Remove the blanking plug from the exhaust camshaft pulley. 2. Remove the exhaust camshaft pulley. 3. NOTE: Hold the camshaft by the hexagon with an open-ended wrench to stop it from turning. Remove the intake camshaft timing belt pulley. 11. Remove the bolts from the variable camshaft timing (VCT) oil feed flange. 12. NOTE: Working evenly in several stages, unscrew each bolt two turns at a time. NOTE: Loosen the bearing caps in the indicated sequence. Loosen the camshaft bearing caps. 13. NOTE: Loosening sequence. Remove the camshafts. 1. Remove the camshaft bearing caps. Remove the camshaft seals. 3. Remove the intake camshaft. 4. Remove the exhaust camshaft with the oil feed flange. Installation 1. NOTE: Use a thumb to press the locating pins of the gasket into the holes. Press a new gasket into the oil feed flange. 2. Prepare the exhaust camshaft for installation. 1. Insert the oil feed ring into the oil feed flange. 2. Slide both components together onto the exhaust camshaft.

SYMPTOM When the engine is first started after the vehicle has sat overnight, customers may “feel” the release of the throttle plate through the accelerator pedal. Some describe it as a one-time “pop” sensation. Customers may have trouble explaining this phenomenon because: They can’t repeat it because it only happens one time, when the engine is cold. The accelerator pedal works normally at all other times. There are no other symptoms. It may be intermittent, happening only during cooler weather. PROBABLE CAUSE The symptom is caused by normal buildup of contaminants in the throttle bore, combined with expansion and contraction of the throttle body. CORRECTIVE ACTION Partially remove the throttle body, and clean it with Honda carburetor cleaner or throttle plate and induction cleaner. REPAIR PROCEDURE 1. Remove the breather tube from the air intake duct, unclip the vacuum lines from the duct, and remove the duct from the throttle body. See Fig. 1 . Fig. 1: Removing Air Intake Duct 2. Disconnect the TPS and MAP connectors from the throttle body. 3. Remove the throttle cable and, if equipped, the cruise control actuator cable from the throttle body. 4. Remove the throttle body mounting nuts and bolts, then slide the throttle body off its studs on the intake manifold chamber. Leave the coolant hoses connected. See Fig. 2 . 5. Put a shop towel under the throttle body, open the throttle, then clean out any contaminants from the intake manifold side of the throttle body with carburetor cleaner or throttle plate and induction cleaner. See Fig. 3 . NOTE: To avoid damaging the idle air control valve (IACV), spray the cleaner through the back of the throttle body, not the front.
