Problem..several garage suggestions so far..turbo,injectors.all the exspensive1s

[galaxy1.9]

Hello everyone,im new here  i have a galaxy and its rough on tick over,engine wobble a bit raspy? (like exhaust blowing) anyway i took it to my local fast fit centre & they said its the turbo on the way out,so i went to another fast fit centre & they suggested a split pipe so i finally went to a garage & they said injectors but following posts on here & various places it could also be the injector loom??? ... im a bit peeved about this as it brings back memories of my Mondeo & endless injector problems,please help & cheer me up a bit with some good news,also the drivers window got stuck today on a day out with the kids & is still down as we speak...i love cars.

Hi and 

First of all is the car new to you (bought with faults) or is this something that's developed.
Has the car been scanned for fault codes, as this will show up if the injector wiring loom is faulty.
What year and engine code is this?
