Yes the problem is now fixed. There is just a hint of hesitation now but it’s far better than before and perfectly acceptable. Not entirely sure what fixed it though.
Here is a list of the things I did.
1. Strip and clean air flow meters, idle control valve and throttle assembly.
2. Re set ignition timing to 10 deg BTDC at idle. (was 14 deg)
3. Adjust base idle to 800 rpm (throttle plates just cracked open and throttle pot reading 505 Ohms) with idle control valve disconnected. (throttle stop was fully shut at idle previously 455 Ohms)
4. Air hoses checked for leaks.
5. Fit new Ford 2.9 Granada throttle cable to correct linkage mounting with clips rather than the bodged bolt and Nylock that came from the factory. Pedal travel now longer but feels better.
6. Check throttle pot on scope OK.
Good luck in sorting the S2

Thanks, I did have the fuel pot changed and it seems to have cut the hesitation but its still there only very slight. Does anyone have a copy going spare of the s series book by Steve heath? It sounds like the one to have. Does it cover spec's etc for things like timing and plug gaps.
