My 98 200sx died out on me after I was sitting at a stop light. The light turned green and I started accelerating around the corner going left when I let off the gas a little then when I started to accelerate again it sputtered out like it ran out of gas. The fuel filter and fuel pump are fine. There is gas coming out of the return line to the gas tank and I am getting spark to the plugs. any ideas of what this could possibly be? There was a car reader attached it but the guy accidently erased the log before I seen the code. I vaguely remember something about vacuum regulator but I m really not sure.
