By Tom & Ray MagliozziI have a 1999 Subaru Outback that I love
very dearly. Last week, the engine light came on,
so I took it to my very reputable mechanic. He
referred me to the dealer, because my "knock
sensor" was off. He warned me that this
would be expensive to fix. Since I am quite poor,
I am wondering if this is a critical repair. What
is a knock sensor? Thanks. - Edith
RAY: The knock sensor, as the
name strongly implies, senses when theres a
knock occurring in your engine.
TOM: And it signals the
computer to yell, "Come in!"
RAY: Thats awful. Engine
knock is also known as pre-ignition. Its
when the gasoline in a cylinder detonates before
its supposed to. It can happen if you have
fuel with too low an octane rating, if the engine
is running hot or the outside temperature is very
high, or if the engine is traveling under a heavy
load - like climbing a hill or accelerating with
a couple of mother-in-laws in the back.
TOM: Pre-ignition is bad for
the engine. If those extra explosions are allowed
to continue over time, they can do damage. The
knock sensor alerts the engine management
computer, and the computer then retards the
ignition timing to correct for it.
RAY: So the answer is that you
should fix this, especially since you love the
car and presumably plan to keep it for the long
haul. Its not an emergency. Its not
something you need to rush out and do today,
Edith, but its something you should fix as
soon as you can.
TOM: The other reason to fix it
is that until you do, your "check
engine" light will stay on. If the engine
develops Another malfunction, youll never
know.
RAY: So Id get it fixed,
Edith. It should cost you about $200. Thats
not cheap, but these sorts of repairs are the
cost of owning a car. You have to expect them
occasionally.

Chase
Predictions
NASCARs
"Chase" for 2006 is over.
So, how did I do
in my Chase predictions? My predictions were, in
order of finishing: Jeff Gordon, Matt Kenseth,
Jimmy Johnson, Tony Stewart, Greg Biffle, Ryan
Newman, Kurt Busch, Mark Martin, Carl Edwards and
Kevin Harvick. Honorable mention "close but
just missing" went to Dale Earnhardt Jr.,
Kasey Kahne, Jeremy Mayfield, Kyle Busch, Joe
Nemechek and Elliott Sadler. My long-shot picks
included Casey Mears and rookies Clint Bowyer and
Martin Truex.
Five out of 10 is
not so good, but who would have thought that last
years top three -- Stewart (champion),
Biffle (second place) and Edwards (third place)
-- would not make the Chase this year? Ill
bet no one. As for surprises, Denny Hamlin is
indeed a big, pleasant surprise, while Earnhardt
Jr., Kyle Busch and Kasey Kahne making the Chase
are not.
As for my pick to
win it all? Matt Kenseth in a close one over
Kevin Harvick and Jimmy Johnson. Just dont
bet any money on my predictions, as anything
could happen and we could end up honoring
youngsters Kyle Busch or Denny Hamlin this
December in New York City. Yes, it is going to be
close for sure.
