My 95 Chrysler Cirrus is getting 8 Miles Per Gallon. The Spark plugs are Bosch ''100,000 mile platinums which was installed ~2years ago and I just put a new air filter in last week. What could be the problem?
 
there could be a number of thing but most common is the o2 sensor when they go bad the stop reading the exhaust oxygen content accurately the show to much oxygen so the computer compensates and in riches the fuel mixture if seen chryslers run so rich because of a bad o2 they fouled the spark plugs (flooded them) they were soaked in fuel so they where shorted out ( no spark) so the car would not start until the spark plugs where either replaced or burned clean with a propane torch. you need a scan tool or a volt meter to check you need to see what the sensor is saying if the signal never goes above .500 volts than it is bad. I would bet that is you problem
 
I bet the check engine lamp is on too.If not it should be.
You best fix it ,driving it like that will cause mo' problems.Like the catalytic converter will be ruined.
 
Nick and zack answers are both probable...My neighbor had a F-150 that started getting 6-8 mpg and no codes etc. dealer couldnt find anything. Finally while running they located a fuel leak in a line under the hood.. never left traces of fuel because it would dicipate and only leaked while running(under preasure)
