any help would be appreciated guys
car started to run like a dog yesterday feels like theres no turbo and you can hear a loud knocking noise from the engine.
ive done the pedal test and came up with this
p0616 - starter relay circuit low
p1316 - injector circuit open/idm codes detected
p1203 - injector circuit open/shorted cylinder 3
p0003 - fuel volume regulator control circuit open
p0303 - cylinder 3 misfire detected

is this right and if so what to do now, is this an easy fix or a costly one
as said any help would be appreciated
