My 1998 V70 has started having a wierd problem, it will die while driving. This usually happens when you left off of the throttle, when the revs drop all of the sudden but has happened at other times. I initially thought it was a fuel delivery issue, maybe a pump or filter but now think it is a MAF, AFM, MAS, POS whatever initials control my fuel/air delivery. I have replaced this piece in the past and understand that they easily get dirty. Any thoughts? Am I on the right page?

Thanks,
Michael
