White would indicate coolant in the combustion chamber, get a combustion gas detector and check it, or pull the plugs and look for crusty deposits on them, if it smell of gas those 4.3l w motor is know for having a leaking fuel pressure regulator, it is under the upper pleninum/ black piece on top of the lower intake.

SOURCE: 1997 Chevy Astro Van accelerates without pushing on gas peddal

You are right to be concerned about this behavior since it can definitely increase your stopping distance.
Either your cable has eaten its way into the inner tubing and is hanging up, or the mechanics at the throttlebody needs some lubrication.
With no engine running, have someone inside to press on the accelerator while you watch for movement of the linkage under the hood. Once you have located it, operate it by hand to see how it feels. If the linkage does not return to the stops provided, then use a heavy-duty penetrating oil to soak the moving parts. If it still hangs, then the cable needs replacement.
With the engine running, tranny in Park and the parking brake on, after you have lubed the visible linkage, have some one inside press on the gas and watch the linkage to see if it now returns to the mechanical stop. Carefully move it by hand to see if it is truly at the limits of its travel where it should be at an idle.

After sitting a day or two unused the v6 will not start in my van


you may possibly have a bad head gasket filling the cylinders with coolant causing a no start,,,,if you see no leaks externally,check the exhuast smoke when it does run for white smoke and coolant smell out the tail pipe,,,,could also do a cooling system oressure check and maybe then youll see a leak,,,check oil for signs of coolant in it,,

Alot ofwhite smoke coming from tail pipe


Have you overheated or are loosing coolant? If not check to see if your transmission has a vacuum hose going to it. (if coolant you can smell it in the exhaust)
I don't think you have the trans hook up but can't remember.

Coolant coming out exhaust, engine light on


when coolant gets into a cylinder it will eather keep the plug from firing or the plug will fire and the coolant will become steam (lots of it ) out the tail pipe and will smell sweet. if this is happening it is a head gasket problem.
