I have a '84 K10 Suburban with a rochester carb and 350 engine. When I
start the car for the first time in the morning it starts at a low
idle. Just a little faster than curb idle. Obviously this causes the
truck to stumble . What's funny is the trucks idle will slowly rise to
fast idle speed after running for about three minutes with the choke
about half open and the fast idle cam in the fully engaged position.
Could this be a vacuum problem (ie: a bad carb to intake gasket). Once
she gets warm I have no trouble at all. Hope someone can help......hell
