QUOTE(Ishley @ Nov 2 2025, 03:45 PM)  I’m wondering if you should check the spray pattern on the fuel injectors. It’s a No cost item. I do 2 at a time on the same side. Disconnect the coil (no sparks during this operation) take out the 10mm nut and pull the injectors out. I use 2 small dishes to place the injectors in… have a helper crank the motor and watch how the injector sprays. It should be a nice fine pattern. I had one that would dribble somewhat and that was the cause of my intermittent problem. It’s an easy fix and it’s free to check. Just a thought. I initially considered the possibility of a failed injector, but I don't believe this would explain the erratic behavior I'm seeing in the noid light. |

That's my thought, either the ECU or a fault in the 123 distributor trigger mechanism. Unfortunately, I don't have an extra to test. I see you are in the northeast, I do have an extra. It's not for a 74 but I doubt it will matter for this test. How far are you from New York? |
