tomorrow I am going to service to clean injectors. They have been thru tough times due to very, very dirty fuel filter that I changed last year(which was there sometime). Although I don't have any serious misbehaving from engine, I think that there is chance for some improvement . I have sticky revs sometimes and idle is little higher than I want it to.
Now , the man who will clean them told me that they have them in the bath for 1 hour and that it is enough to do it properly everytime. So I am asking all of you who have done the same service to tell me if this would be enough and what would be MINIMAL flow rate on them after? From new it is email@example.com bar for crems. They charge me 350 dinars per inj (3.2 GBP) which is bargain even here in Serbia. So I am not sure if this would go OK, although I know that they have powerful cleaning maschine...
