Nissan QX Throttle - Peter D
A friends Nissan QX 3 years old. When cold it won’t start without a little throttle but once started you need to keep a bit of throttle on for a mile then it is perfectly ok for the rest of the day. I have not had chance to look at it but assume the stepper motor is not kicking in. NO ECU detected Faults. Any known faults with this one or suggestions what else can cause this. Regards Peter

Nissan QX Throttle - Aprilia
That's quite a new QX then - A33 series? What's the year reg.?

99% sure its the thermo-element. A simple 'wax-stat' type device that sits under the throttle body and holds the throttle slightly open in cold conditions. As engine warms up it progrssively closes.
Idle air valve might also need cleaning.
These problems are easy to rectify.

If you want longer descritption and more precise information etc., and part no. of thermo-element then e-mail me at:
