I was getting about 25 mpg or so, have been since I got the car in november, its always run rich. Well, now for some reason, the car is getting about 10 mpg. WHAT happened? It still runs the same, no leaks, but theres a really stong fuel smell coming from the engine compartment. ANY idesa would be greatly appreciated

Uh, possibly a fuel leak? If so, poor fuel economy isn't your biggest problem--- the fire hazard is.

Start the car up and do a thorough search for fuel leaks. Do not use a match.

I can't find any leaks, I had the car up on jack stands and traced the fuel lines all the way from the tank to the carb..... all dry, even put a big *** piece of cardboard under the car and let the car run, different rpm's , and then let it sit for a while, the cardboard was dry. I'm stumped

Gas drys very quickly you wouldn't have been able to tell with cardboard underneath the car.

frigidmonkey

if you get gas on cardboard, even after it dries , you can still see where it was if you look carefully

Could it be that your gas gauge is malfunctioning and you think its empty when its not, therefore giving you bad readings?

I dont know. thats pretty weird

frigidmonkey

the gas gauge never worked... I go by the odometer and how much gas I put in it.... I should have had another 20 miles or so, and ran out..... then today, I ran it dry again :[
10mpg

The fuel companys are mixing in alchol to strech the fuel so they can gain more profit means the cars burn more fuel try getting gas at another station . just a thought my car was doing the same thing went from 30mpg to 20 mpg i switched stations and it fixed the problem

frigidmonkey

thanks, I wish it was that simple, tried three different stations in the last day and a half

That sux i didnt kno gas companies were doing that

RotaryRyan

Gas companies suck. arent they charging enough already?

enigma32

Isn't the government taxing you enough already?





You're not spewing fuel somewhere at the carb by any chance? (i.e., at a gasket, where perhaps it might just vaporize?)

RotaryRyan

True

frigidmonkey

the carb reeks of gas, but I can find any spilling out, my exhaust smells like gas too, like I have raw gas going right through my engine, but I still have plenty of power

Quit driving like a badass but thats impossible.

go to this thread and see if that help you out i think its flooding your car and taking compretion out buy dilooting the oil thats gets injected in your routers

frigidmonkey

flooding while its running? that would suck. I can't figure it out, I checked the float levels, and they SEEM to be ok. its the racing beat holley

not realy my brob was when the key wAS off the some thing was stuck and made it flood when the key was off and that would barke up the atf i put inside so it could be flooding when its off see if you get better mpg when you just run the car with out turning off for long

My truck had a milage problem and a strong fuel smell near the rear... No puddles though and I lost about 1/8 tank overnight (parked). Turns out a steel line was rusted. It disintegrated in my hands. Check all the lines. You can never be too sure.

If it's rusted, wiggle it.

If there's rubber line, bend it...

When it breaks you know your culprit. Unfortunately you better have a ride to the parts store.

Do you trust your neighbors? Had a buddy who started getting realy bad MPG...looked out his window late one night and saw his neighbor siphoning gas from his tank.

RotaryRyan

Evil neighbors!
