I have a 1992 Saturn sl1 and over the last 8 months my fuel economy has gone from 40+ to upper 20s. I also have not lost a considerable amount of power, if I did not record my fuel mileage I would not know that there was an issue. I have did a vacuum test on to check the catalytic converter, tested the oxygen sensor, checked air filter, and pulled the spark plugs. Nothing points to a clear answer. If I cannot figure this out soon I will have to start driving my truck that gets 18mpg to save gas money!
