I've been toying around with the idea of giving my car a tune up. I know, at 34,000 miles it's pretty early in the car's life to think about this, but I figure that since fuel prices are only going to continue to go up, the return on investment would come pretty soon.
As far as engine health, I do know from my used oil analysis from Terry Dyson, the engine's wearing well but with a lot of fuel dilution. Ignition timing was something that I flagged when I examined the data from my AutoEnginuity, since spark advance just tended to be kinda low/somewhat retarded.
I was thinking about making sure that the valves and timing chain were properly adjusted...along with assorted stuff like EGR and PCV valves.
Would I be better off trying to check this stuff out myself, or take it to a shop and have the car given the old 'once-over'?
