timing chain should be checked... After you replace the distributor,
rotor, plugs, wires, Coil, filters... check your timing chain for too
much slop.

Actually Bill, most people who perform their own maintenance replace the
oil, and a cheap K-Mart Fram filter too, every two thousand miles, because
they like changing oil.  They replace spark plugs at ten thousand miles or
less, because the old ones look a little stained.  The intervals quoted in
the owner's manual are, as everyone knows, a little conservative and this
guy deserves credit for pushing the envelope.  It looks as if he is getting
around 50k from transmission fluid, and 80k from spark plugs, and that is
not bad.
