Engine miss, spark knock, buck/jerk, surge and other driveability concerns may be caused by induction crossfire. This occurs because of improperly routed spark plug wires. ACTION: If spark plug replacement is performed, the correct firing order and spark plug wire routing is essential to prevent the possibility of induction crossfire between cylinders. Refer to the following procedures for inspection of the spark plug wire routing and firing order. Properly reroute the spark plug wires if required. FIRING ORDER ^ The firing order for 1987-1993 vehicles is 1-5-4-2-6-3-7-8. If # 7 and # 8, or # 2 and # 4 spark plug wires are routed next to each other at the separation bracket, an induction crossfire condition can occur. ^ The firing order for 1994 vehicles is 1-3-7-2-6-5-4-8. On these vehicles the # 1 and # 3, or # 5 and # 6 spark plug wires must be separated to eliminate the possibility of an induction crossfire. ^ To eliminate the possibility of the coil wire becoming disconnected, route the coil wire under the spark plug wires at the distributor cap. 1987-1993 VEHICLES

Engine Electrical > Firing Orders Firing Orders To avoid confusion, always replace spark plugs and wires one at a time. Replacing spark plugs and wires one at a time will help prevent incorrect wire routing or cross-firing resulting from an incorrect firing order. If more than one wire is to be disconnected at a single time, be sure to tag all of the cables to assure proper installation. Also, be disconnecting the cables, compare the firing order and routing to these diagrams and note any differences for installation purposes. This will help assure the wires are properly installed.

NOTE: Keep all foreign particles out of the transmission. 1. Warm up the engine to normal operating temperature (the radiator fan comes on). 2. Park the vehicle on the level ground. Turn off the engine. 3. Remove the dipstick (yellow loop) (A) from the transmission and wipe it with a clean cloth. 4. Insert the dipstick into the transmission. 5. Remove the dipstick and check the fluid level. It should be between the upper mark (B) and lower mark (C). 6. If the level is below the lower mark, pour the recommended fluid into the filler hole (A) to bring it to the upper mark. Always use Honda ATF-Z1 Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affect shift quality. 7. Install the ATF filler bolt (B) with a new sealing washer (C). 8. Insert the dipstick back into the transmission.

REMOVAL CAUTION: All spark plugs installed on an engine, must be of the same heat range. Spark plug CHAMPION: RC10YC4 NGK: BKR5E-11 (Alternate) NGK: BKR6E-11 (Alternate) RH SIDE 1. Disconnect the ground cable from battery. 2. Remove the resonator chamber. 3. Remove the spark plug cords by pulling boot, not the cord itself. 4. Remove the spark plugs with spark plug sockets. LH SIDE 1. Disconnect the around cable from battery. 2. Remove the two bolts which hold washer tank, and then disconnect the washer motor connector. 3. Disconnect the rear window glass washer hose from washer motor, then plug connection with a suitable cap. 4. Hang the washer tank away from working area. 5. Remove the spark plugs cord by pulling boot, not the cord itself. 6. Remove the spark plugs with spark plug sockets. INSTALLATION RH SIDE 1. Install in the reverse order of removal. Tightening torque (Spark plug): 21 No.m (2.1 kegs.m, 15.2 ft.lb) CAUTION: The above torque should be only applied to new spark plugs without oil on their threads. In case their threads are lubricated, the torque should be reduced by approx. 1/3 of the specified torque in order to avoid over-stressing. LH SIDE 1. Install in the reverse order of removal.
