2004 Nissan Quest Q&A
2004 Nissan Quest Question: What causes engine bogging and loss of power in '04 Nissan Quest w/no warning?
It is not ease to diagnos a "modern"vehicle if there is no Check engine light on and that full of all kind of sensors. But by the symptoms i would think a clogging catalytic converter that blowing back fumes to engine. But i am just guessing. That would be best to take it to a professionl shop. - euromech
