    What causes a Nissan Pulsar to blow its ECU?

    The throttle body becomes porous where coolant seeps through and shorts out the idle motor, which in turn blows the ECU. If you remove the case from the ECU, you should be able to see a ‘burn’ mark on the board. If it isn’t so bad, it can be repaired. If it’s bad, you need a new or second hand ECU. Your cost will be higher!

    What should the idle speed of a car be?

    This rotational speed allows the engine to generate enough power to operate vital components without turning off. The idle speed should feel consistent without skipping or slipping. In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth.

    When an engine is running at idle speed it generates enough power to smoothly operate equipment such as the water pump, alternator, and power steering but not enough power to move the vehicle itself. A passenger car will usually idle between 600 RPMs and 1000 RPMs. A properly functioning idle should run smoothly without skipping or slipping.
