When i shift to drive, and the rpm reach almost 2000, it fluctuates down 1400- 2000, and it can't reach higher than 2000 rpm,,

It start,, Idle is ok,, but when i accelerate theres a time that the engine was hesitating,, i cant drive it even it is partialy inclined road,, or even i hang it,, it always surge when it comes to drive shift, Could the fuel pump give this kind of prob at the engine?

MY subaru legacy 96 was stalling when i shift to drive and the rpm was playing on 1400-2000,, i change the ignition coil, high tension wire and tps,, but it always stall when i shift to drive,,
