I would like to get a couple of injectors tested, mostly because I want to know their flow rate.
Were I in the UK I would post them to the likes of Mr Injector UK, or look for a local fuel injection specialist in the Yellow Pages…
Anyone know of an injector cleaning/testing service here? I do see many garages offering a drive-in service, I think they just pour some injector cleaner into the tank…
No there are services here, even, in ‘Darkest Brittany’, Redon, where they don’t just ‘pour stuff’ in the tank 
But you don’t say where you are 
Ah yes, stating where I am would be sensible 
I’m in Aveyron, close to the Tarn border
