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 |

My bet is on fuel pressure or fuel delivery.
But listen to what James or Rob adds. They've BTDT. That is quite the engine bay. Check fuel pressure first.....and make SURE none of your fuel lines are kinked otherwise you will chase your tail. You didn't say where the fuel pump is located.....in the front? Good luck. |

I had the more flexible German fuel line under the tank but I switched everything over to the high pressure FI hose and this stuff does not bend nearly as well. I did notice a kink in one of the lines but think I solved it. I will double check. Thank you! |
