sick '93' Imperial

["Mark Swingle" <mark.swingle@xxxxxxxxx>]

The 90's Imperial has an early version of the check engine light and
diagnostics retrieved by cycling the ignition key.  Try this and see if your
Imperial tells you anything:

I would suspect an O2 sensor as when they fail, they fail rich.  If it were
my car, and the O2 sensor was bad, I'd change the oil afterwards.  You may
run so rich all the gas is not burning.

Also, if the roughness is from the engine, you could have a plug, plug wire
or coil pack problem too.  And don't overlook the air filter while you are
checking things out.

Bumpy ride, rough ride might be shocks/suspension. Gas
mileage may be the efi system however.

For instance, the computer uses the oxygen sensor to
see how rich/lean you are and fine tunes the engine
based on this information. If the o2 is off or bad,
things may not run perfectly- and gas mileage would
suffer.

Other things could also play into effect on this, such
as tranny problems, error codes, etc.
