I've just changed the air filter in my car ('91 Dodge Colt Vista) and it's no big deal to change the spark plugs. I've been getting the car tuned up by the dealer every 2 years (every 24K miles) but I'm wondering if I can skip that this year. Aside from changing the air filter and spark plugs, is there anything that gets done during a tune-up that would be unwise to skip?
