good news. I've had the ever fammos bucking and stalling problem that no one can figure out what causes it. I sent it to my mechanic and he's had it for about two weeks now but no luck. he did replace the throtle sensor and he said it runs a lot better but it still does it. I told him to keep the car as long as he has to, and he's a nissan mechanic so hopefully hunt the problem down, I'll keep you'r guys posted (for those who have simular problems.
