It turns out that my suspicion about injector was correct and after cyl 3 injector was replaced with Bosch reman one - it is working.
But hours later I got misfire code p0300 (multiple/random cyl. misfire) and it misfiring on low idle. I going to clean MAF sensor today with liquid cleaner and hope it will help (but I am not sure it is the reson for p0300 alone). It is too cold to do it right away, will wait till noon.
It might be fuel filter as well but it is major headache to get it replaced in Quests (even proceeding from inside) so I will continue to eliminate other possible sources of misfire first...
