Default Throttle Position Sensor on CFI Unit

Hey peeps ! First time for me on here so hopefully I will get some good help. Certainly looks like I will after reading a few previous posts.

I have a 1994 Ford Escort LX 1.4i and have a slight problem with it starting from cold. The problem is that it finds it hard to start from cold unless I apply the accelerator peadle slightly.

After a bit of reading on the internet and looking at the bits under the bonnet and also reading the Haynes Manual I have discovered that it looks like the Throttle Position Sensor doesnt move when the car is running. Now my understading of the function of the TPS is that it will adjust the acelerator cable so that the car starts without trouble by applying the right amount of revs... correct me if im wrong about that.

After removing the TPS I noticed that the wires to the TPS were showing and looked like they had been touching so possibly shorting it out or something similar so I want to replace this. Only problem is im finding it hard to find a replacement without going down to the scrappy. Can anyone help with this? Anyone know where I can get one online? It has the markings on the back saying its a weber PF07/03 if this helps.

Also I was reading up that its controlled by the ECU... do you think there is any chance that the ECU could be giving out faulty signals or no signal at all to the TPS?

If anyone has had similar problems or any other suggestion =s for what might be the cause then please feel free to advise.

Sorry its so long for my first post but I wanted to make sure I got all the information across ! Thankyou for taking the time to read this.
