I’ve put a 1993 4l80e transmission in it that runs on toggle switches to bypass the computer for the shifting of the transmission. But my question is, does the transmission shift speeds have anything to do with the spark advance? Because I can’t get any power out of the engine. I’ve replaced the distributor cap, rotor, plugs wires, and set timing to the book, but the engine still bogs down on acceleration. But it runs fine at idle. Fuel pressure is at 9-13 pounds, compression is 120 psi on all cylinders.
