intermittent problem:- have had fuel pump replaced two years ago, plugs and leads just replaced, coil pack been replaced, crank shaft sensor replaced. feels like the car is starving of fuel, but this has been eliminated. its running 35psi on fuel pump. feels as though the car is going to stall, then gets a surge of power to run ok. will idle fine at times then feels like it drops out and feels like its missing. the car feels like it is going to stall when it idles very rough. the car is a 2000 auto Hyundai accent.

 

Check for vacuum leaks or leaks in the intake manifold.
