Skyline Sensor Issues?

*mods please feel free to move this if its in wrong section*

Hey guys, I have just bought an r32 with an rb25det, It is running like crap at the moment, feels like its missing, and has a big delay in throttle, and it idles at 1500.

I believe it is not to do with afm for various reasons.

There are three things im concerned about

1. Picture 1 is a blue plug which was not plugged in when I got it, so im just wondering what it is? and if there is any reason why it shouldnt be plugged in on my car

2. is the TPS, I noticed there are three wires which have been circled in a little red circle which have been cut, im wondering what these wires are?

3. there is a coolant temperature sensor on the top hose of the radiator, which is currently plugged into nothing.. Im wondering where it should be plugged into. I thought this could be one of the problems because once the car gets warmed up and iv driven it for a few minutes it starts running alot better (still idles crap)
