Thanks to site member Alex B, we now have some excellent procedural instructions which demonstrate how to perform this commonly needed repair operation on your CG13DE engine.
It has been noted as a common problem for k11 micras to suffer from some dry solder joints inside the throttle body's electrical compartment. This can make the car have terrible fuel consumption, jerky/rough idle, loss of low to mid range power and intermittent stalling.
If your micra is suffering from these symptoms, we strongly recommend you download and follow these instructions as this has been proven to solve problems on many peoples' micras.
