Well, if done every third or even fourth oil changes, based on 5000 miles, we're looking at $300/year, that's about $25 a month. However, at this point, as I said, it could do more harm than good until you get the blasting done. Not to mention that this is a really simple procedure that you could do yourself.
On the other hand, carbon build up may not even be the issue here. It very well could be electronic, a bad injector, harness issue. GM has field service manuals for every product they sell. In there, are trouble shooting protocols, if the tech follows this, the problem will typically be found. At this point, they are probably just moving down the list. The good news is that if they have already done the 'wear and tear' portion, the rest of the list is probably going to be warranty stuff, let's hope.
