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.

INSPECTION PROCEDURE 1. Remove the steering column covers. Refer to section 17 of the appropriate service manual. 2. On the lower side of the ignition switch, look at the interlock cylinder cover: • If the cover is square, the ignition switch was already replaced with an updated part, and a key interlock repair kit is not needed. Go to step 3. • If the cover is round, go to REPAIR PROCEDURE. REPAIR NOT NEEDED REPAIR IS NEEDED 3. Reinstall the steering column covers. 4. Center-punch a completion mark above the seventh character of the engine compartment VIN. REPAIR PROCEDURE 1. Remove and discard the plastic cover from the ignition switch key interlock solenoid. 2. Note the position of the interlock solenoid plunger; you’ll need to install it the same way. 3. Remove the screw from the solenoid, but keep the solenoid attached to its electrical connector. Discard the screw. NOTE: • Be careful not to lose the solenoid plunger; it slides out easily. • Keep the plunger free of dirt and grease while it’s removed from the solenoid. 4. Note the position of the interlock lever spring; you’ll need to install the new spring the same way. 5. Attach the slide hammer to the interlock lever pin, and tighten the slide hammer clamping bolt.

SYMPTOM Excessive cranking is needed to start the engine after the car is driven and then parked (with the engine off) for about 15 to 20 minutes. The engine stalls a few times before it begins to run smoothly, and the MIL may come on with a misfire DTC stored in the PCM. PROBABLE CAUSE In certain areas where the climate is very cold during the winter season, oil companies sell fuel that is specially formulated for improved cold weather driveability. If the weather is unseasonably warm in these areas during the winter season, the lower boiling point of this fuel causes the fuel in the lines to vaporize, resulting in a hard start or a misfire at start-up. NOTE: This condition occurs primarily in New York, Pennsylvania, Ohio, Indiana, Illinois, Minnesota, and Colorado. If you are not located in the states listed above, contact your DSM before doing any of the following repairs. Otherwise, your claim may be debited. CORRECTIVE ACTION Replace the fuel pressure regulator and the PCM. REPAIR PROCEDURE 1. Download the immobilizer information from the PCM in the car with the PGM Tester. Refer to S/B 00-049, Immobilizer System (Type 2). 2. Write down the customer’s radio station presets. 3. Disconnect the negative cable from the battery. 4. Remove the fuel fill cap. 5. Place a shop towel over the fuel pulsation damper, then slowly turn the damper counterclockwise to loosen it and relieve fuel pressure. 6. Tighten the fuel pulsation damper, and torque it to 22 N.m (16 lb-ft). 7. Disconnect the vacuum hose and the fuel return hose from the fuel pressure regulator. FUEL PRESSURE REGULATOR
