I am coming to my wits end with this problem. I purchased my 1998 volvo V70 XC in August 2001 with 17,000 miles. I have been experiencing occasional "bucking," (for lack of a better description) as if there is a miss in the engine. I notice it mostly at speeds of 50-75 mph. My dealer cannot find anything, and of course, since it is not occuring at all times, they haven't felt this happen. They say no codes come up on the diagnostics. Does this sound familiar to anyone, and do you have any input?
