Why is my car stalling in curves?

When I'm driving a little faster the engine loses power immediately when I come into curves until G forces are low again. It only does this when the fueltank is starting to get on the emty side, although there's still alot of fuel left for say atleast (probably moore) half an hour city driving. So not completely empty.
So the fuel in the tank moves with the g-force to the side of the tank when cornering.... but what has happend to the fuelpump when it can't seem to get gas??? Is this a common problem? What can I do about it?

the fuel sloshes to the sides of the tank, and the pickup is at the bottom, so there is no fuel at the pickup. It's hard on your fuel pump to drive it without a lot of fuel, as the fuel pump is kept cool by the fuel.

solution? fill up the tank.

its not a flaw 90% of cars on the road dont have baffles its just you dont notice cause most of them cant creat the cornering forces a camaro can. the higher performance camaros did have them like the IROCs.

But if the IROC had it then shouldn't the GTA have it as well??

only G92 cars had it.. with the 1LE racing package. when my car is at 1/4 tank, i cant accelerate thru a corner, the fuel is just pushed to the side and the pump cant pump any fuel to the motor. my car has some pretty good G force capabilities.

i'm not sure if GTA's had it.. only Z28 1LE camaros have the baffled tank that i know of

wow, I didnt think anyone was having the same problem as me...

My car loses immediate power whenever I round a corner now, I didn't think it would end like this.

you have something else wrong if it does it at any more than 1/8 of a tank i have just a base SC and i can take a corner at 40mph at wot and it wont stall of even hint at it unless i am in the orange. im not talin a bout a shallow corner either im talking about a 90* corner from a 4lane highway to a 2lane and i stay in the outside lane the whole time.

It definately does it on my car before the orange point. I don't believe it could have been like this when it was new. Something isn't working right.
What could cause this?
If anyone has a pic or illustration of the pump and/or the inside of the tank it would help alot. Please post.

I might but I doubt it, I think when i am turning at full throttle mine wont do it either b.c it is using the fuel that is in the lines, I think I just need the baffles since it only happens when not accelerating through the turns.

My 1989 IROC does it too ( non 1LE ) If I got like a 1/4 tank and I hit a clover leaf gonig fast , I can feal it bog and sputter.


the 1LE tank I hear has a 360 degree rotation fuel sender aswell . SO that would help .

Another simple solution. Slow down.


If you are corning that fast, you might want to watch the oil pressure gauge too. Oil can move away from your pickup too.

I know someone who burned up his LS1 camaro road racing because the engine was being starved of oil.

my car does the same exact thing(92 ,305,T-5)...my sending unit is going bad so that is the only way i know when my car is at about 1/4 tank...im fixing to do a 350 swap and change the pump so i figured i would wait till then to swap it....what year and type cars have the baffle in the tank that will fit in my 92 so i can price one...i might just replace the whole tank and pump at once..

Would using synthetic motor oil reduce the chances of this happening? I have heard that syntec leaves a layer of oil along the walls and doesnt let things like that happen. I have also heard of storys of mechanics forgetting to put oil back in the motor after an oil change and the cars running for like a half hour before something goes... so does cornering too fast really do that much damage?

Car: Yes
Engine: Usually
Transmission: Sometimes
Axle/Gears: Behind me somewhere
It's not a "flaw"; it's an "undocumented feature".

Yes they all do it. Other GM cars do it too. Other mfrs cars do the same thing, although it might not be in turns; it might be braking or acceleration as well. Whichever direction the fuel can run off to when it gets low, that's the condition the motor will run dry of fuel.

Don't let your car run so low of gas. It's hard on the fuel pump besides, because the pump is cooled by the fuel. It will burn up if it gets run alot in an empty tank.

No, synthetic oil will not keep the fumes in your fuel tank from sloshing away from the pump.

I wasnt talking about oil in the fuel tank, i think i know a little more about cars then that lol i was refering to a statement made about why cornering at high speeds is not good for then engine and one of the things said was it can starve the oil pump... it was a little off topic so i apologize.

So would not having baffles in the gas tank cause my gas gauge from going up and down when I brake and accelerate? Or would that be something else?

My 88 Iroc always did that, full tank or not. I didn't read all the posts, but people told me it was an oil pressure problem.
