Could be, though I'm no expert and can only guess - hoping the collective knowledge on here can point to what may have caused it.

It has been running WAY TOO rich off boost for a few months, and me being a fool kept driving it, as when my car works (which it does very little) I LOVE using it.

I don't know what to do next... I have a huge frown on trying to work out what to for the best.
