I have a 2004 Tahoe with 5.3 flex and since im on layoff right now I'm bored and got thinking my Tahoe has 134xxx miles and I have never changed the plugs coils nothing except oil changes and filters. what's everyone recommend for plugs ? how often need replace coils? any other tune up information would be great too!
