1998 Mercury Sable
3.0 V-6 single cam
Okay, I don't know what the difference is between these three. My dad,
who was a mechanic for 20 years, always called the sound I'm hearing
"clattering". A friend of mine calls it "ping" and a mechanic I talked
to Tuesday afternoon called it "chattering". Well, whatever one I have,
it's doing it pretty badly on 93 octane when accelerating or maintaining
cruise speeds up a hill. I use premium because it clattered on 87 and
Here's what I've done:
1. Replace spark plugs.
2. Replace spark plug wires.
3. Purchased upon a spark plug wire tester and I tested
each wire at idle. All wires are receiving power.
I revved the engine while testing the wires. All
wires are still active.
Things I haven't done:
1. I have not paid the Ford dealership $73.99 to
diagnose to pull the engine codes.
2. I have not replaced the O2 sensor because the
mechanic where I bought the car said he put a new
one in when replacing the rack for the steering
mechanism. I believe him because the people at this
place are very good and they have bent over backward
to get the car in line after I'd already bought it.
In fact, today, even though I bought the car back in
April, the mechanic *gave*
me a new hood latch
release line to install because the one that was on
there when I got it was broken and I stopped in
today and he said it had come in.
3. I have not replaced the knock sensor.
4. I have not replaced the fuel pressure regulator, the
fuel pump, the fuel injectors or the coolant sensor.
