Dstc service required

[grezmo]

Hey all

I had this fault about 6 weeks ago and it resulted in injector number 4 being changed. I am now getting the dstc service required light up again but this time it is not going into limp home mode. It comes on and then when it changed gear, it's automatic, it revs and then is very jolty. The power bar on the digital display suits at the bottom.
The engine doesn't sound that course in comparison to last time when they injector went so I feel like it is something else.
Going into Volvo shortly to see if they can fix but I'm considering a new car now as it's one thing after three next.

Thanks in advance
