burned Bosch rotors and tune-up question
        Check your cap and lead wire interface.  I have seen all too many
times vans come in my shop with the wrong lead wires for the installed
distributor cap and coil.  There are two distributor caps & coils available, one
intended for the 1.9 engine and one intended for the 2.1 engine.  They are
interchangeable.  The interface connection for the lead wires are different.  If you
install the wire leads for the 1.9 cap & coil in the 2.1 cap & coil or vice versa
you will get arcing at the connections and thereby arcing at the rotor which
is what is destroying the rotor.  The best scenario is to use the 2.1 cap with
its positive connect porcelain end lead wires.  If you install the 2.1 cap &
lead wires on the 1.9 then you MUST change the end of the lead wire to the
coil to the connector for the 1.9 system coil.  Always use dielectric grease on
the lead wire connections and boots making sure the boots are a snug fit.
