Has anyone replaced the plugs on a 2000 malibu (or similar motor)?


I wanted to have the 6 plugs on my 2000 Malibu replaced and I was told
it would cost $191 to do it. Is there that much labor in the job?


It's an American lack of engineering intelligence. Replaceable parts
should be accessible.


They ARE accessible. The normal maintenance interval for spark plugs
is 100,000 miles. They really don't need to be super-easily accessible
if you only have to change them every 100,000 miiles.


Actually, if the engine is not sucking oil down like it's on sale,
there's no reason to ever change them.


Even if the plugs don't get fouled by oil and carbon, the electrodes do
gradually erode. I'd bet that the gaps are somewhat wider after 100K
miles than when they were new.

Hmmm,
Platinum or Iridium plugs last LOMG time!- Hide quoted text -

I have 127K on my 2002 Pathfinder. I monitor every drop of gasoline
that goes into the vehicle, and do a cumulative interval mileage check
every 4K or so. So far I have not had any decrease in mileage, so I
have to assume all cylinders are firing ok. I won't worry about
replacing the platinum plugs until I see the mileage showing signs of
decreasing.
