Alfa GT JTS 2.0 idle shaking
I just bought an 2005 ALFA GT 2.0 JTS with 6m warranty. Around 60k miles on it
It had a belt/waterpump change, new plugs, check up etc.
It was shaking when idle though, not a lot, but noticeable in the seat. And the shaking was off to one side, like a jump on one side, landing on another. I took it back and the garage read out that a bobbin (x2) was bust. They put two new ones on. Now I have the feeling the shaking is even, but heavier. Garage says that an 2.0 always shakes.
What is normal for an Alfa GT 2.0? I know the shaking of an V6, but this just seems too much for an 2.0 engine... Or could it already have a lot of carbon buildup with 60k? And needs cleaning, or something else?
Thoughts appreciated, because I can get it fixed in the warranty period.
