I have a 2001 ford windstar SE. Recently the gas mileage has been very poor. What can be the problem?
How long since your last major tune up?
Maybe a year.
That should still be ok then. Might want to check your air filter tho. Any other drivability issues? If not I might would try a can of sea foam in your gas next time you fill up. Also check your oil. If it has a gas smell to it you might have a fuel injector sticking open and leaking gas while engine is off. The sea foam will help if this is the issue also.
