Q: How to check and replace spark plug wires,Distributor Cap and Distributor Rotor on Toyota Celica?
A: Inspect Spark Plug wires when installing new plugs. If found, remove wires. After the engine cools, inspect the distributor cap as well as the rotor. Also, inspect each wire individually, marking its location. Disconnect from the distributor, check for corrosion, and replace. Buy a set for your engine model and replace one at a time. When installing a cap, move wires one at a time to prevent mix-ups.
