Need help to find mechanic

Hi guys I need the help I'm looking for trustfuly backyard mechanic familiar with Volvo d13 in Tampa Florida area
Please don't say Nextran those guys put me almost in chapter 7

 

Let me tell you something those guys have tools they have proper software but they dont know how to use them i have misfire on cylinder number 5 and low compresicom 46% diagnose bad injector replace them charged $2000 after that I drove 5 miles and I got exactly the same problem but now computer doesn't show any codes so they say must be something else we have to keep looking I'm sick and tired to spend money for guessing

 

This is 2012 Volvo d13 doesn't require special tools

 

I know what you mean but the strange thing is when they level all injectors on the computer the engine start working Nice & smooth for the next 5 minutes the injector number 5 fuel pressure start gradually increase and bumping noise increase too there is no any smoke from exhaust pipe so with my understanding mechanical problem like you said supposed to be appearing all the time Another strange thing the missing noise only you can hear only on idle when I increase RPM over 1000 missing sounds just disappear this is doesn't make any sense I spoke with the bunch of mechanics nobody have a clue what's going on
