    Default Pay for tune up?

    As a kid I always did the work on my nova, 1972. Now that I'm 50 and vehicles are more complex I have not done any work in years. I want a tune up on my Colorado, 2004, 3.5 liter. Nothing in the way, I have the air intake without resonator box so plugs are easy to get at so is it worth trying or do I pay 300.00 + dollars to have it done. I need more acceleration.
    2004 colorado 3.5 vortex I-5. 5 speed stick. 235-75/15s runs great. Just painted and rust proofed. Looking to install cold air intake and new exhaust. Better gas and more power.

    I would say most guys on here would probably go with the "do it yourself" route. If i remember correctly, those are an inline five cylinder arent they? Should be pretty cut and dry.
