i have a stalling issue with my 1999 altima. it satlls randomly when decelerating. when it dies i get no lights. the engine just quits. i do get some stuttering when i accelerate at times also i have replaced the fuel filter and the distributor cap and rotor all to no avail. any ideas on this at all. i get no check engine light or anything and i had the car smogged 2 days ago and it passed with flying colors. thanks
