Default Fluctuating Cosworth Engine

When cold, my Saphire 4X4 (92) engine fluctautes wildly. Even when driving along, the revs drop to almost nothing and then comes back on.

Any suggestions - Please....

Sounds like your idle valve or the base idle speed is incorrect.

If the revs pick up from a very low idle, it seems the ISCV is working OK. Get your car down to a garage to get them to set up the idle speed and CO.
