Engine and Exhaust

CATALYTIC CONVERTERS
On vehicles equipped with catalytic converters, the following conditions must be observed:
- Use only "UNLEADED FUEL".
- Avoid running out of fuel.
- In case of poor engine operation (misfiring), avoid driving the vehicle and correct the problem as soon as possible.
- Do not disconnect any spark plug wires with the engine running.
- Avoid push starting the vehicle.
- If running on a dynamometer, make sure the catalytic converter is well ventilated.
- To prevent burns, use caution when working near the catalytic converter.

OXYGEN SENSORS AND SILICONE
To avoid damaging the sensor, do not use silicone based products on an oxygen sensor equipped vehicle.

COMPRESSION TESTING
When performing a compression test, remove the fuel pump relay fuse and disconnect power to the ignition. This will stop fuel flow to the injectors and prevent engine from starting.
