From the pic I posted on first page you can see the Pedal Pot and the grey cable is behind the carpet near that. As yours is probably a left hander then it will be reversed. Have a **** good route around behind the carpet and you will find it...
The location of the connector is shown in the photo Phil attached. The connector is under the carpet to the right of the accelerator pedal - it will probably be tucked down so you'll have to pull the carpet out from under the trim around the door to find it.
If the bottom plate on the plenum is loose the engine will idle at 1500-2000 rpm depending on how bad the air leak is - mine didn't result in rough running just a high idle with limited boost, so I'm not sure that it's the same as your problem unless yours is just starting to undo.
Good luck finding the problem.

What does the diagnose tab look like?
You've got a keyword response so the comms are working.
Update on the current car start up situation
1. Reluctant to start, need to press the throttle to help
2. Once started, engine rough and idle at 1300
3. Press throttle, jerky engine and with backfire
like firework
4. 5-10min or so everything seems back to normal
From the screen dumps, it looks like he's done everything but read the status on the diagnose page... he might just not have mentioned it.
Online says - if you don't have any error codes present when you read status, it could well be one of the faults mentioned in the thread already - many of them don't throw codes (although the MAP DTC did on mine when the plenum plate came loose).
Yes for sure if you can get codes from the car this is much better and it will give you some ideas of where the problem lies, including the temperature sensor.
