Sudden drop off in mpg
My '95, 8 valve, automatic used to get 27-28 mpg on a consistant basis. Recently it dropped off to 20-21 mpg. No real change in driving habits or distances. What would cause such a sudden drop off? Car seems to run the same as it has all summer. I have let it warm up a bit longer with the colder weather, but not that much longer. Thanks in advance...
