Standard Ignition Distributor Cap P/N:JH-77
Standard Motor Products
Whether you need a 4Runner distributor cap for a 1988-1991 Toyota 4Runner or a replacement for a 1988-1991 Toyota Pickup, the Standard Ignition JH-145 is a direct-fit cap that helps route high-voltage spark to every plug wire. It houses the distributor rotor and carries current from the ignition coil, through the spinning rotor, to the terminals that feed each spark plug wire in firing order. See the "Vehicles it fits" section for engine details.
Signs a distributor cap may need replacing include cracks, carbon tracks, or worn and corroded terminals inside the cap. You may also notice misfires, hard starting or rough running. Other ignition parts can cause the same symptoms, so diagnose the cause first. If the cap is at fault, JH-145 replaces it.
