further thoughts on spark plugs, coolant sensors and engine starting

hi all,


I've been doing some further thinking about it, and
I'm just having some thoughts about how engines work.....

Mechanic #4, the one who did the work, told me that the problem
with the bad spark plugs was what was causing the engine to be
flooded with gas, which caused the rings to become washed.
When I heard that, I wasn't so sure it made sense, because the
spark plugs basically just provide the "spark", right?

When I heard that If the sensor tells the computer the engine is
the wrong temperature then it gets the wrong amount of gas at
startup, I thought that was probably what caused it, not the bad
spark plugs.

So mechanic #4 told me he had to clean the gasoline out
of the engine (isn't that weird - engines are supposed to have
gasoline in them), but that the rings were still ok. But then I
looked at the invoice, and they don;t have any such kind
of labor work listed on there. All it says is: replace ignition
cable set, replace all six spark plugs. That's in addition to
the diagnosis. So: what if that is all they did - what if that was
what it needed to be able to get it to start again, even though
it still doesn't start without problems?

Hmm..maybe a better to put it would be: could the coolant
temp sensor cause the engine to become so flooded that it
doesn't start? Or could the spark plugs cause that, though I
don;t see how? Or was the mechanic just telling me something
he thought I would buy?

I'm wondering, because I'm working on formulating my complaint
against this guy.

TIA!

PS the car is working gingerly. I am trying to be real easy on it
until the part & book arrive.
