Depends on the tune up. If it's just plugs and wires and your doing the work it's around $50 bucks. If your doing a complete tune up with plugs, wires, fuel filter. PCV valve, breather, new air cleaner, and injector cleaning then your looking around $300. if your having a shop do the work for you labor in most areas is around 90 to 100 an hour. plugs and wires can take about 30 minutes. the complete tune up can take up to 4 hours.
