I finally got the ignition and fuel pump hooked up on my 76 2.0 L and the engine cycles between reving and stalling when I hold the pedal down to get a fast idle. What do I need to be checking now?

On the top left side of the ECU, is your adjustment knob. Usually has a rubber cover on it the size of a dime. Regarding your trim pot, that's not factory. The PO might of had that hooked up to the cylinder head sensor on cyl #3. Check to make sure that head sensor is hooked up. That also can cause running issues. Hope that helps. At least your fuel pressure is good.

At least your fuel pressure is good. I have a wire connected to the cylinder temp. Not sure if it is the right one. There is what appears to be a brown wire in the bundle that resides near the distributor that I thought might go to some sort of sensor located behind the distributor towards the rear of the vehicle? I'll check the wiring as described above and also try to determine what the trim pot in the wiring harness is all about. I've been hooking the less obvious wires to mating connectors in the same general vicinity. I know that is not a best practice but...where else would they go? Over on the driver's side near the front of the engine is another brown wire with a female spade connector behind the air pump. Not sure where that one goes. |
