The rear Sora changer on one of my bikes seems to have gone "floppy". By this I mean that it while it holds the chain tension when the chain is on the large front chainwheel, it has suddenly stopped doing so when the chain is on the middle or small chainwheel.
As far as I can tell the gear cable is not snagging,
The bike was second hand so the rear dérailleur is of uncertain age. Could the spring in it have gone and if so is this replaceable?
