How to check and install spark plug wires, Distributor Cap and Distributor Rotor on Toyota MR2?

Inspect spark plug wires when installing new plugs. Look for arcing or sparks in a dark, ventilated area with the engine running. After cooling, examine the distributor cap and rotor. Disconnect each wire from the spark plug, checking for corrosion, burns, or cracks, and ensure a tight fit. Inspect each wire at the distributor end for corrosion and fit. Replace any damaged wires with a pre-cut set for your engine model. Check the distributor cap for cracks and worn contacts, and the rotor for cracks. Replace if damaged. Measure resistance between wires and cap; replace if it exceeds the maximum value. When installing a new cap, transfer wires one at a time.

Toyota MR2 Distributor Cap

Toyota MR2 cars have one of the most important and sensitive parts called the Distributor Cap that facilitates current transmission from the ignition coil to the spark plug wires. It shields the interior part of the distributor and also holds the rotor in position that supplies the high electrical voltage to the spark plugs as per sequence. The distributor cap also has terminal towers that correspond to the number of cylinders in the engine; the possible features include dual spark plug per cylinder or wasted spark. The distributor cap must be checked and replaced quite often because the signs of a bad cap are rattling, die hard starting and stalling, and backfiring. Lastly, water can negatively affect an engine; hence, the distributor must be clean, and there ought to be a proper R, or gasket for the distributor to perform as anticipated. On the whole, the distributor cap is an essential and very easily serviceable part of the MR2's ignition system, necessary for the proper functioning of the car's engine and sometime used as a rudimentary security mechanism.
