Chevy's 1996 Astro Van came equipped with the same 4.3-Liter V-6 engine that had been in use since the first Astro models rolled out of the factory in 1985. A distributor-based ignition system separated the spark plug wires into two banks that ran along both sides of the engine to the spark plugs. Engine problems, such as surging, rough idling, hesitation and a lack of power are often associated with a failing spark plug wire set. Removing the spark plug wires for inspection or replacement is fairly straightforward and can be accomplished by most Astro Van owners, providing that care is taken to reinstall the wires in the same order they were removed.
