This (3rz) car will start, it can idle but it will not move if you try revving it will just cut off. Fuel pump is fine , spark plugs are good , the air flow sensor is also good , but there is an unconnected plug with three wires (green /yellow, green/black, green ) in the same loom with the airflow sensor. i also don't know where it goes.

Hi,

I just went through the entire powertrain management wiring schematic. The only thing I can find close is the throttle position sensor. Take a look below at the pic. Recheck to see if the "black" wire is actually dark blue /black. Also, recheck to see if there is a black wire with a yellow tracer. It can be hard to see colors when they get dirt on them.

Let me know.
