Operation CHARM: Car repair manuals for everyone.

Engine And Exhaust

1. Use "UNLEADED FUEL" only.
2. Avoid running out of fuel.
3. In case of poor engine operation (misfiring), avoid driving the vehicle and correct the problem as soon as possible.
4. Do not disconnect any spark plug wires with the engine running.
5. Avoid push starting the vehicle.
6. If running on a dynamometer, make sure the catalytic converter is well ventilated.
7. Do not use silicone based products on an oxygen sensor equipped vehicle to avoid damaging the O2 sensor.
8. If fuel injected, 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 the engine from starting).
