To replace the spark plugs on a 1987 Toyota Supra, first, ensure the engine is cool and disconnect the negative battery terminal. Remove the ignition wires from the spark plugs, taking care to label them for proper reinstallation. Use a spark plug socket and ratchet to carefully unscrew the old plugs, then install the new ones by hand to avoid cross-threading, and tighten to the manufacturer's specifications. Reconnect the ignition wires and the negative battery terminal to complete the process.
Take it to the garage. Text equipment is needed to diagnoise it.
