Whenever I floor it I burn almost an entire small green line off the gas gauge. My friend said that I may have header leaks and I would have to replace something that goes between the headers and engine. It's not creating enough back pressure so it just shoves gas out into the exhaust or something.
What is he talking about? Can I do this myself because it's really killing my wallet. I can't race because of it.
My car is 1987 V6 LS.
Are you sure its actually using that fuel? When I floor it with my buttstuffog gauges, especially around the 3/4 mark, it may drop down 1/4 to 1/2 a tank...it doesn't mean I actually just burned all that fuel (and for some reason, I'm currently getting the same mileage per tank whether I zip around town or drive slowly).
I also have an 87 3.8 and when I floor it the gas gauge goes down but a few minutes later it goes back up. It is not very accurate. When I get to the empty mark it still has 3 to 4 gallons left but that is ford for ya.
your friend is full of it...but anyways
everyone is right, its not that youre actually burning it that fast, the gas just sloshes around in the tank
lol your friend is a tard, the only thing between the headers and the engine is the gasket. does your friend drive a Honda or similar? cuz they usually don't know anything about backpressure, or cars in general. the only way gas would be shoved into the exhaust would be if your valve timing was totally FUBAR, or you were running super rich.
you forgot to mention...does the gas gauge go back up after you stop flooring it? or maybe there's a flaming trail of gas on the ground wherever you drive?
that's because you go slow everywhere :ies: i keed, i keed
You friend would make an excellant header gastket and salesman (woman).
That's usually how a$$holes rip people off automotivly.
lol, does he sell headlight fluid?
Dont worry, if this is the case, you need to go downhill and you can recovery more fuel than you have put in the tank.........jeje...

I know that backpressures have different effects on two strokes, maybe he is more of a two stroke guy (*snicker*)
One way to get better mileage is to put air shocks in the rear of your car and pump them right up, that way your car is always traveling down hill and you will consequently get better mileage :ies:
Yeah it goes back up, but not to the same position it was before I floored it. I tap the panel and it goes up a little bit.
cant really kid when its the truth...i can speed, but it takes a while
I don't know if this is the case for all gas tanks, but in my '87 5.0 the sensor is definitely in the front of the tank...when I'm pointing downhill the gas gauge increases and it decreases when I'm pointing uphill. If I tromp on the gas the gauge naturally drops. My guess is that this is what you're seeing.
As a side note, it's the opposite in my Explorer, and a lot more severe. The gauge *really* drops when I'm pointing downhill in it, and it's sometimes a pain keeping the two vehicles straight in my head as to the float position in the tank.
Get to test my freeway mileage tomorrow. Going to visit family in Seattle through friday
