Re: Car falls down as it leaves line
 

I had a VERY similar problem a few years back. LONG story short, it was the battery. My battery was mounted lengthwise in the car at the front and apparently it had a cracked plate or two. When I would launch the plates would touch and ground out I suppose and the engine would flat die but then it would recover and run fine the rest of the run. Hope this helps.

Make sure you have the gasket between the top and the body taped where the secondary metering rods go through it. Gas can come through there and cause a stumble.

I'd go with Greg's answer. He had the same problem with the Buick. Time for new tape!
