Report #1Mrs. Price, 1996 Mercedes-Benz E320, 147,000 mi
RookieThe car was acting strange, staggered engine start, shaking, cutting off. The check engine light came on, took to shop and mechanic said Mass Air Flow Sensor was bad. Had the part replaced and no other codes have come up but car won't pass emissions.
