well, give us some better numbers. How much fuel did you get for your $20? Some places are reaching 3 bucks a gallon for the stuff, that would give you at best 7 gallons.

Granted, this is still pretty bad miliage, because even at 6 gallons for your twenty and 60 miles (62 is 100kilometers) that is ONLY ten miles to the gallon. It almost sounds like you have a massive fuel leak.

Might it have something to do with your second 02 sensor? I'm not sure why you don't have a CEL with no cat at all though, it's usually hard to avoid even with a cat installed after you put in a header.

My last 13.76 gallons of gas got me 410 miles, mix of flooring it in the city and 70mph highway.

Did they check your O2 sensor and Injectors were clean? Maybe there's some build up on the O2 sensor, because I had that problem in my last car, and I took it to a mechanic and they cleaned it off and it was fine after that. If not, maybe you have something in the way of your intake? I don't know man, I'm thinking something is blocked or the sensors are dirty...my .02

If you turn your car on and let it sit at idle does any fuel gather on the floor? It really seems like you have a fuel leak, I think this is beyond a tuneup. Also, at idle, does feel boggy (getting too much/too little fuel) or is it like it always has been?

no gas on the floor, and it idels fine,

but when i got my headers installed i had 2 changed my 2nd o2 sensory b/c the check engine went on so it cant be that b/c its a new sensor.

I know that a gallon has 4 liters. not 3 liters...

1 gallon- 4 liters..

so. ... $20 of gas are 5 gallons.

100miles-5 gallon = 25 miles/gallon.

its not so bad, I guess everyone here got almost the same mpg.
