just another suggestion it seems that all you guys with fuel mileage problems have older model year contour/mystiques i read in the "how to articles" section of this site about a fuel pump change in the 99 model year. they changed from a returnless type to a return type. i dont know which one of the two is on my car but i have a 99 so i my have the newer return type whichever i get a lot better mpg than some of the guys on here somebody might want to check that out though. fuel pump is pretty crucial and if the older one seems to be very strong it might be maybe too strong to get the desired mileage thus ford makes a change. possible? just a theory my crazy mind came up with but if you guys are as desperate as you sound (trust me with some of the probs ive read about id be desperate) give it a looking into. good luck hope someone finds some help from this idea.
