Ok here it is i have a exhaust leek from the passanger side of my car it sounds like a exhaust donut but when i took it apart i didnt see the donut thing but there is a spacer like thing between the manafold and the y pipe i was wondering what could be causing my leek i only hear it when i am giveing it gas and it is kinda loud an annoing

And when i get down to a 1/4 tank the car runs like crap and acts like it is out of gas

 

Look For A Crack In Your Exhaust Manifold. Fuel Problem Could Be Trash In Your Tank Or A Weak Fuel Pump. Sick

 

When your gauge shows 1/4 left, you could really be just about out of gas. GM fuel gauges are notoriosly inaccurate. Some "brain' in GM decided that the gauges be off so that people would think they were getting beter gas mileage than actual. Next time you are at the 1/4 mark fill up the tank and see how much gas it takes, you might be surprised.

 

So true. We laugh when the tank starts to get that low. Accelerating will cause the guage to go up, decelerating down. And yes 1/4 tank is just about empty.

 

i havent had that problem. my needle goes about 2 millimeters below the e mark when its ocmpletely empty, and my dumbass has ran out of gas many times.

 

Appparently you gauge is not working per GM specs, and you should replace it immediately. LOL
