My 1990 wagon has been giving me some trouble. It would run fine and then all of a sudden start to buck (kind of jerk you around, like if someone continously punches the accelerator in 1st gear at higher rpm) on the highway in 5th gear. Then it gave me problems starting, it seemed like it was flooded, I would depress accelerator and start fine, but when rpm dropped back to idle it would stall. Anyway, I had it checked out by a non volvo mechanic and he said its the mass air flow sensor. Does this sound right? How difficult is this to replace? how much should this part cost me and could I do it myself (I did do all the mods at the bottom of the page myself)?
