looking for 1 injector. Small vibration as a reason, Tech2 test failed

Got a strange vibration at 1500-2100 rpm and a bit of engine shaking at cold idle. At warm engine - nearly no vibration but powerloss after 2800 rpm.

Tech2 data is OK at all time(rail pressure, fuel selivery and ets), Injectors test failed - #2 clicks only once, all others does 5 clicks, as should

I thought maybe someone has a spare injector for sale? or knows a place where to buy them in Australia? Have to replace one only due to financial reasons

Thanks a lot

Sergey
