Lyon's Muffler & Brake

Mr*** brought to my shop a truck that he had recently purchasedHe was concerned
because it did not run properlyUpon inspection it was discovered that two of three catalytic
converters were plugged
After an agreed price for the repair, I found that the damaged
converters were not a victim of
wear and tearThese units were ruined by a severe misfire in the engineThey were
melted insideThere are more than a few reason's a ~meltdown~ can occur: The converters
were superheated due to a raw fud condition in the exhaust flowThe excess unburned fuel
ignites when it strikes the hot ceramic catalyst within and drives the temperature above the
operating condition of the converterThis ceramic catalyst is unable to withstand
the extreme temperature and begins to meltThe ceramic collapses and the converter is
destroyed
The condition that led to this meltdown could be the result of a number of malfunctions
including faulty oxygen sensors (*** did not want to replace sensors) an incorrect fuel
mixture, worn spark plugs, ignition timing, faulty injectors, etcthe list is long and *** was
informed of the detailsI recommended a local mechanic that I trust to take care of my customers
I told *** that he hould take his truck to a qualified mechanic immediately or the same thing

will happen and there will be NO warranty on parts damaged by engine misfire
He said that he understood, paid his bill and drove away - right pa t the mechanic that
I recommended! After a few days*** came back with the same problem (converter meltdown) claiming
that the parts I sold him were defectiveI gave him a price that would cover my cost (with
overhead) and he was not interested
I value my customers and sympathize with Michaels health issues, but it was Mr***'s
negligence that mined parts purchased at Lyon's
