Bad gas mileage!!
Filled my tank, reset my trip odometer. Car had about 1/16th of a tank left so I went to the gas station to fill up again. How many miles did I make it? 115.8 miles!

The gas tank is 15.6 gallons on these things, so that's roughly 7.42mpg. Any ideas on what I can do to increase my gas mileage? I've already done the following:

Cleaned MAF
New Plugs
New Plug Wires
New MSD Cap N Rotor
New MSD Coil
New Fuel Filter
Techron Fuel System Cleaner
K&N Air Filter

What else can I do? MSD Ignition Box? Different car? lol

pull one of your plugs and see if you are running rich. Did you try pulling codes?

How are you driving the car? Are you on it all the time? Is this city, freeway, or mixed milage?

The plugs are kinda tan, I guess that means the ignition is too far advanced? When I got it, the thing was at 20* BTDC, so I put it back down to 10* BTDC. I don't have a code scanner, AutoZone told me they couldn't do 94-95 Mustangs and that I'd have to take it to the dealer to run a diagnostic on it. Not gettin' on it, suppose to be a daily driver. It's city driving.

A friend of mine and I went out tonight, he had the same thought that the cats might be plugged. The thing is a dog until 40mph, then it opens up and screams.

Tried to power-brake it and it just revved to 1000rpm; Didn't spin the tires, didn't move, nothing.

Also has a real small vibration in the steering wheel @ 35mph in 3rd but if I have it in 2nd and I'm doing 35mph there's no vibration? Hell I dunno.
