popping from the carb..

[mudrunner80]

Once in a great while sitting at a light, when I give it throttle to take off it'll pop from the carb. Its only done it a few times and few and far between. Its an 88 1500 4x4 350 auto with 157,000+ miles. I have'nt checked anything yet. Just looking for ideas.
Thanks in advance

there is a diaphram in the throttle body injection that ruptures..then at idle it drips out fuel,,,,,too much for engine to handle..
