I have a 93 altima (standard) that I got from a friend. She told me when she had the car, it would occasionally stall while driving. She had it looked at a few times, but no reason for the stalling. Since I've had the car, it happened to me. Actually, it starts bucking first, I pull over, and just before I am stopped, it stalls. Sometimes the check engine and oil light come on and sometimes they don't. I only have to wait a minute and I can drive again. That time it was on the highway. Other times it was on side roads. Sometimes a week will go by with no problem and other times it will happen repeatedly. I brought it to my mechanic and still no reason for the problem. HELP!!
