Three months after I bought the car the transmission went out.
The head gasket went out at 78000 miles.
The fuel pump was replaced at 85000 miles.
The ignition switch was replaced.
The blower motor was replaced.
The oxygen sensor and the map sensor have been replaced.
The Front Struts and Mounts were recently replaced.
Up until recently the car has been a great dependable economy car in-spite of the transmission problem the first few months.
Recently the car's fuel economy has dramatically dropped from 27 MPG average to 20 MPG average. Two different mechanics can't find anything wrong with it.
Have someone check your EGR valve. If the valve is stuck open you'll have a massive vacuum leak right into the intake which will cause that kind of mileage reduction.
