I cant figure out why I only get about 150 miles to a take of gas if im lucky, I only average 13mpg and I was thinking there is something wrong with the car. Ive already had the computer scanned there were a few codes and everything was fixed. But the gas mileage is still horrible. I was wondering if there was anything else I could do. The car has 3.73s, full exhaust and an aluminum driveshaft. Also its a 5speed. The car has new spark plugs, wires, air filter, fuel filter, cap and rotor. Thanks

I get anywhere from 180-220 miles to the tank... It's pretty stock... all new plugs, wires, cap, rotor, timign set at 14, 93 oct., O2's, But I don't drive it like a grandma.
Yes, they do here. You can easily pull codes yourself, or just buy the $30 tester like I did. Hook it up, push start and it will do all the work for you and get the codes.Blakthorn said:
catman, do you know how old the O2 sensors are? How light are you on the throttle, usually?
i dont know how old the o2's are but they werent throwing any codes. could they need to be replaced even if there arent any codes for it?, im pretty easy on the gas but i get on it once and a while. when i got the car checked, it came up with an egr code and a vacume code but the guys at the shop fixed both those problems but i havent seen any improvement in mpg.
Contrary to any beliefs you may personally hold, the emissions gear does not hurt gas mileage. When all the gear is working properly, the computer tunes the car for best possible mileage at cruse.jaackal said:
Here's a book that will get you started with how the Ford electronic engine control or "computer" works.
Ford Fuel Injection & Electronic Engine Control 1988-1993 by Charles Probst :ISBN 0-8376-0301-3.
It's about $20 from Borders.com see http://www.amazon.com/ . Select boo...very good, and I found it to be very helpful.

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.

IF your car is an 86-88 stang, you'll have to use the test lamp or voltmeter method. There is no functional check engine light on the 86-88's except possibly the Cali Mass Air cars.
Codes have different answers if the engine is running from the answers that it has when the engine isn't running. It helps a lot to know if you had the engine running when you ran the test.
Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2 digit codes and 3 digit codes.
