[MV850T]

Since my last post, and about 5 other mechanics, including one called the "Volvo Doctor"

EGR Sensor? replaced, Mass Air Flow Sensor replaced, Fuel Pump Relay replaced, still the same problem. The next step is the or a computer? Apparently ther is 3?

I was getting an appraisal done today on it for my student loan, I just happen to meantion the problem to the guy who did it. He said he has a BMW who does the exact same thing, but only in cold weather. He said his problem was the computer.

Replacing it this weekend, if this doesn't work, we have tried everything, and I am going to have to sell it (very cheap due to this problem).
