Ok , so I have the engine running but it needs tuning. A little background, rebuilt stock 2.0 with D Jet, running a 123 dizzy. It fires right up and idles a little rough at first then smooths out. It revs fairly well and sounds good. The problem starts under load, it starts to stutter a bit.
I have not messed with the adjustment screw on the ECU or tried adjusting the throttle position sensor, or been able to check my fuel pressure. I’m hoping to rally any troops in the north Florida area to help me get these final details ironed out. Thanks in advance, John |

Looks gorgeous. None of those things besides fuel pressure will help you assuming the tps was installed correctly. Hopefully someone close can pop by. If you want to do the basics yourself, go to a flaps and rent a fuel pressure gauge, make sure it is 29lbs. Make sure the timing is good. Do you know what they set the 123 to? Is it Bluetooth or pot? That alone could be your problem. I see the advance port on the throttle body is plugged.
