|sqzbox||Another shot in the dark would be check motor mounts and the steering linkage with wheels turned right to see if there is anything happening down below like a starter wire being rubbed or something.|

Also fuel related- be sure the accelerator pump arm is in contact w/the linkage so there's movement of the pump diaphragm the instant the throttle is moved. Just be sure there's 0.015" clearance between the arm and linkage at WOT.
But if it's fuel related, I'd be rather surprised. I'm thinking electrical/ignition related. Chaffed wire, something rubbing, that sort of thing.

|Malibu1347AD||Only seems to happen from stop and goes... or slow to fast sharp right turns. Almost only from stop and go.|

I would look at any wires that are attached to the fire wall or inner fenders. These flex a lot when turning and I have seen more than one instance where they have scuffed through and will short out.
This is assuming your float level is ok. Most likely if it was not you would be having issues turning either way.

I'm finding it hard to see a "water in the tank problem". I doubt that an electric pump or manual pump could circulate fuel from the tank to the carb in the time it takes to turn right at a corner. Even with a total loss of FP to the carb, there would be enough fuel in the bowl to run a right turn.
Does your problem happen at a stop and go right turn, or whenever your turning right as on a curve in the road? Knowing exactly when the problem occurs will help diagnosis a lot. Right turns are sharper that left turns from stop and turn for example. I don't believe it's float level because it would do it left or right as fuel slosh works both ways. It wouldn't hurt to check though
because your betting on the guy who set the floats at the factory has a perfect record and never makes a mistake, LOL

|SSedan64||I wouldn't add any more fuel. Get a few bottles of "Heet" brand water remover. It's basically pure alcohol. Pour a bottle in with the gas that's already there and drive it, try to mix it up a little "wheel back & forth". When you're about empty add a few more gals. & 1/4-1/2 bottle & run that out. See how it does, if it makes a big difference or stops you can probably fill up & add another 1/2 to whole bottle for good measure.|

All grounds are in place. I've got intake to firewall, battery to alt bracket and chassis, and another one can't remember where. Checked them earlier.
SSedan... I'm wondering if you might be on to something there. B/c when this started happening I hadn't driven the car in weeks/or over a month... I had only started it every other day or so to keep the oil up in the motor. Hmmmm so what can I do to help fix this..... Full tank of gas and what additive should I use?

|SSedan64||Could also be water in the tank. I have a Mazda that did that, accelerating & turning right it would die, as soon as I straightened the wheel it would pick back up. Just like I switched the key on & off. Drained the tank + several bottles of Heet later it finally fixed it.|

If the engine is not grounded to the chassis and body then it could be loosing ground. You should have a ground from the body to the frame, engine to body, engine to frame and battery ground from battery to body/frame and it wouldn't hurt to have one going to the engine. A lot of times these ground straps get removed.
Had a fellow that had an older ford truck. When he turned on the headlights it ran bad, when he turned them off it ran good. Turned out that the ground strap from the body to frame was missing. When the headlights were on they were grounding through the ignition module that was mounted on the fender well.LOL
As you turn the engine could be shifting and loosing its ground.

|sqzbox||Check ground strap from engine to firewall also.|

Well I have a holley blue inline pump on it w/new line from the top of the tank all the way to the regulator and carb.. even have two filters on it... But I'll check anyways, never considered the ignition wire but I would think it would have to be the 12v wire to the distributor to cause that and that wire is good... hmmmm
|08-30-2010 10:58 AM|
I had an old Ford P/u that did that....Turned out to be a cracked rubber fuel line from the tank to the frame rail. When the frame twisted the crack would open and break the suction from the block mounted fuel pump. If you didn't hurry up around the corner it would begin to stumble lean.
Since a carb swap didn't help i would look for a fuel source problem. Of course a loose wire in the ignition could be doing the same thing.
I hope this helps you at least with ideas.

Sputters when turning right from stop
My 79 malibu for whatever reason sputters if I make a right hand turn from a stop. It bucks a little bit then picks back up. It started doing this w/my old carb... I just put a brand new holley 4150hp race series on the car. It's starting to do it now w/this carb. Could this be a float adjustment on the primaries? I haven't changed anything w/the fuel system when the problem started... so I don't see how it could be anything there... I'm frustrated at this point.. any ideas?
