| Was wondering if anyone could be of assistance.......I own a 1998 Volvo S-70........ I have a very vast knowledge of autos......but not really specialized in one type of car.....this Car has had a "Check Engine Light" on for some time.....I have had it to 3 different shops....and within 30 min. of driving away.....that light that they just shut off, comes right back on ....... the info I have is from a generic scanner.....code PO 172 comes up....and I am not sure which parts can cure this code.......so far they have only changed 2 oxygen sensors..... with the 2 sensors....nothing was cured......Also, one of the flow charts I had them print showed something to do with Fuel Trim, on that particular code.....Any Clues.....can you help ???? ........... What parts do i need to solve this problem........thanks Bill |
