Stopped running, replaced injector pump and fuel injectors.

Now since work done, surging under load, high pitch squeal and back firing.

Vehicle had done 97500kms.

What was repaired:
Injector pump replaced and injectors due to injector pump failure and metal in fuel system.

Has been to another shop prior where they removed the timing case and broke it having to reset the engine timing after moving the car in gear they reassembled the timing case.
