I got a 91 camaro rs 3.1 and it has a hesitation when accelerating from a dead stop. Like if I am at a stop light and when I step on the gas it goes but kinda cuts out and jerks then when the speed picks up it runs fine it will get up and go. I replaced the stock injectors with some ACCEL 17/lb injectors. I have a new fuel pump and new filter. I don't know if it might be the throttle position sensor or something. Any feedback would be great thanks

 

maybe new fuel pump, might be wrong but the injectors may not be getting the right amount of fuel, just a guess tho
