AX Throttle Fault

Hi people. Good to hear the meet went alright, shame I couldn't make it.
Anyone got any ideas where to start with this one? A friend has an AX 1.0 'K' plate. It broke down and had to be towed-the fault is this (this info is second hand from the AA man to her to me so apologies for the vagueness). The car will idle but apparently when the throttle is pressed the engine won't run properly, it chugs and misfires making it undriveable. The AA man apparently said something to do with some switch or something in the throttle. I don't know much about AX's and I haven't even had a look at the car. I don't even know if it is carbed or injected although if we are talking about throttle position switches or whatver then it must be injected.
Any ideas?
Once again apologies for the poor info, it's not much to go on I know! Thanks.

I have looked on GSF they don't sell a throttle potentiometer for any AX, closest I can find is ignition coil and ignition module. Anyone know?

No reason to suspect the TP first off.
At least the wire connector on the TP should be tried first of.
If the TP gets defective, the engine will commonly have scaring haunting idle problem, but rarely would be undriveable.
I relly think you should get hands on before deciding for any parts.

if i remember corectly the throttle potentiometer comes as part of the monopoint unit (well at least from citroen) which is quite expensive.
like Anders says get hands on before deciding that its faulty,from the symptoms you describe it could very easily be a partially blocked cat or a crankshaft position sensor breaking up internally under load.
