not as dealers, as thy seem to be giving you way more than a fair shake - that car has depreciated in a big way since you bought it what with the 0% financing on new cars out there the used mrket is pretty low priced

but as mechanics

seriously, these problems are the kind that could be traced to something as simple as a vaccuum leak. I think Bay 13 at volvospeed has a bit on replacing some of the plastic elbows which are likely locations for a leak.


But a vac. leak will mess with the air-fuel mix, which can then burn out an O2 sensor, and may show up as a throttle body sensor fault instead. With al lthe nifty computers the car can mask the high or rough idle symptoms you might ordinarily see with something htat simple.
