Hello
Welcome to TDP :):):D:):)
The misfire is likely a failed injector.
Any SES LAMP Showing ???
If so get the codes
With the engine running (And missing) crack open each injector line (one at a time) and see which one does not cause a change... Sort of like pulling a spark plug wire on a gas engine to isolate a misfire...
Once you locate the cylinder not fireing... Remove the injector and switch it to the cylinder next to it (just swap the two) Restart the engine and see if the issue follows the injector.
If the issue follows the injector then the one injector is bad for sure.
If the issue does not follow the injector then there are other issues such as the injector pump ??????
The vacuum pump will not cause the issue, but you need to get it fixed to have the engine operate properly (Turbo boost and power)
Good luck...Keep us in the loop
