My 1996 mercury mystique idles high and low then smooth, sometimes stalls when I give it gasbackfires, and looses power.I replaced the fuel pump, fuel filter, fuel pressure regulator, and spark plugs, but still the same problem. Can you tell me what could be causing these problems?Please help ASAP. Thank You.
