I have a 97 villager and at initial cold startup, the vehicle will start, but then idle down like it wants to die. I have to rev the motor for like 15 sec and then it will be fine, and it will be fine as long as the engine is warm. If this was an ordinary Ford motor, I would clean or replace the Idle Speed Control motor becaus ethis is exactly what it sounds like, but the Nissan motor has no idel speed control motor.
I have cleaned out the throttle body, mass air meter, but it still does it.
I have found NO vaccume leaks either.
What can anyone suggest I do now.
