Thread: Identify these wires?

Recently my car has been acting up when i start up the car when the engine is cold. It starts up fine, but when idling it would drop all the way down to 200-400 rpms as if its going to cut off. I would have to press on the gas until the engine is warm enough to keep a steady, but rough idle. But if i start up the car when the MAF is unplugged it idles perfectly. I have already tried two different MAFs and they both have the same symptoms. I looked for vacuum leaks and i could not find any. I spotted these two wires (GREEN&YELLOW). I want to know where these wires supposed to wire up to and maybe this is what is giving me the weird idle problems. The harness is found behind the transmission and it seems to go down to the starter?? BTW, the car is a 93 g20. Thanks

Could be that one sensor on your tranny. Cause that black one is for the tranny and the one next to it should also be for tranny. Should be by the driver side on top of tranny.

Thanks man. I just dont know where the green/yellow wires supposed to connect to. The black plug I checked but it does not look like the wires connect with it.

The yellow and green wires have a grey plug on it and goes to the sensor on the driverside of the trans that sits down on the bottom.
