I have the car listed above z28, I just bought it and had been sitting for 4 years. So, I changed the fuel pump, drained gas, new fuel filter, installed headers, new plugs and wires, and a new throttle response sensor. It starts right up but really sluggish has no throttle response. Any help would be great. Thank you in advance.
