Borrow a throttle potentiometer to temporarily substitute for his.This is the simplest first check,they are a source of all sorts of bother on the 12v,eg the symptoms you describe,cutting out at road junctions,bad or non existent idling and uneven acceleration.Price new makes a mess of £50,so best to test it first.

IACV as Gozz so correctly identifies is the MOST likely culprit. If its not that then look at the ignition module in the distributor. That is where I would start.

I had a non starting 12v V6 and i suspected the tps ( before i had my FDS 2000  ) My local Ford dealer sugested unplug the tps and try and start it if it starts straight away its the tps .
A failed sensor that gives no output is bypassed by the EEC-IV or V but a failed sensor giving a false output can cause a contant problem or a non run situation

MAF is a good runner up of the list of free fixes (or whatever a 1/10th of MAF cleaner spray costs  )
Another cheap fix was to replace the DTPF sensor hoses, easy to access, in total the consumed materials were 2-3 euros. Paid off itself instantly, my average fuel consumption went down with 1.5 litres per 100km.

It,s a 12 valve don't forget,they don't use a MAF or EGR system.
