What Is Involved in a Tune-Up for a ’06 Pontiac Vibe? – Spark plugs have always been the main part of any tune-up. In older vehicles, a tune-up entailed a lot of work, including maintaining (or replacing) the distributor cap, ignition rotor, spark plugs, ignition wires and ignition timing. In newer vehicles — like the 2006 Vibe — a lot of these systems are automatic and no longer require maintenance.
The only necessary parts for the tune-up on a 2006 Pontiac Vibe are the spark plugs. The Vibe has a four-cylinder engine, so it uses only four spark plugs. Pontiac recommends only Iridium-tipped spark plugs, which must have a preset gap of .043 inch.
