Thanks for your reply-I suppose I think they're complicated because I don't do much work on cars, The last cars I worked on were my Peugeot 505 turbo diesel's, Miata (basic maint. ) very simple.
I read posts on this site trying to learn and perhaps share a tid-bit of info. Everything is way over my head!
I'm planning some basic tune up jobs this week-end, Spark plugs,wires,rotor,filter (air), fuel if not too hard-just basic stuff I can handle. Will see what happens and go from there.
