I've heard of coke, oven cleaner etc but there's surely has to be something on the market that's stronger & more effective in situations like this??
A friend has the misfortune of having to work at one of these recently. He tried a couple of slide hammer tools, WD40, all sorts of other products, oven cleaner etc over weeks.
Renault themselves actually sell a tool specially for removing injectors. Downside is that it costs about £800. It does however work.
Your local dealer may rent you the tool.
