I have a 86 Jimmy with a 350. When Im stopped and just gun it, it stalls out on me, but if I gun it, and it starts to stall, if I let off and gun it again, it will take off. Please help me figure this prob. out. I have a new carb ( holley truck advenger), spark plugs, wires, dist. cap and rotor, control module, and capacitor, and accel coil. I put all these on to resolve the problem, but it didnt.
