really sounding like a newbie here i know but what all is involved in a good tune up. id like to do it my self but want to know what all is involved in it or if it would be better for it to be done by a professional. barely had an lt1 for about 3-4 months now so still learning about it. any help would be nice. thanks.

 

Plugs and wires are a PITA but can be done with time and a few beers. As far as everything else, look at changing the fuel filter, cleaning the injectors, clean the MAF sensor (if 94 up car). change all fluids if possible. Hope this helps!!

 

Exact same as above + look at the air filter while you are at it.
