Will a bad alternator cause new spark plugs to smoke?
Spark plugs don't smoke. A bad alternator would cause a dead battery.

Blown head gasket. Or a missfire cause by a bag ignition coil, fouled plugs, too little fuel pressure, timing is off ect.
What would cause black smoke out of exhaust under heavy acceleration?
Balck smoke usually means the engine is burning rich - that is to say, more fuel is being delivered to the combustion chamber than can be ignited by the spark plugs. Keeping a good tuneup schedule and clean-up/replacement of sprak plugs will prevent, or at least minimize the black smoke under heavy acceleration.
1991 dodge shadow 2.2 auto What would cause the mixture to be rich The problem im having is black smoke and Im guessing fuel and you have black dry soot on your plugs and very poor gas mileage?
It could be a bad oxygen sensor or the wiring to the oxygen sensor. This is not the only possibility. Could be a computer issue. not sure what else. If the spark plugs and O2 sensor are all black, then the injector may have failed.
Can bad spark plugs cause smoking from under the hood of a car?
Not likely. Smoke from under the hood denotes a leak. Either your coolant or oil is leaking. White, thick smoke is oil. Could just be a gasket. Thinner hazy smoke is coolant. Check your hoses. Look for fluids/wet spots. Bad plugs can missfire, and make your exhaust smoke.

Why is your 1997 Dodge Grand Caravan smoke black?
it could potentially be because its old or if you dont get oil changes that is most possible From va6yag: Actually, it could be a few things. One cause of black smoke could be that you're "running rich"- in other words, the fuel/air mixture that is being burnt in the cylinders is not correct- there's more fuel than air. This could be caused by incorrect timing, a faulty EGR, damaged valves or your computer not mixing the fuel/air in the correct ratio. Another cause may be faulty spark plug leads, or fouled spark plugs. Your best bet is to get a tune up done on the van, along with an oil change and a radiator flush. That will eliminate the spark plugs, leads, air/fuel mixture and the timing as possible causes of the black smoke. If that doesn't solve the issue, you could be looking at something far more serious. Get the van looked at by a competant mechanic.
