I have a 1991 civic hatch with a d16a6 i have recently got the car running and i drove it to work the other day well it was kind of sluggish until it hits 2k and then it took off pretty well at idle the car hick ups almost every once and a while and then i drove it home that night and as i accel it sputters almost and had a hard time getting up to speed i put new plugs wires rebuilt dizzy fuel filter and valve cover gasket in the car and this problem still exists im thinking mayb the fuel pump but im not too sure just wanted to know if anyone had some suggestions thanks

 

Is this an Si or is it a DX/STD? What fuel injection system?

Have you checked the cam timing?
