21 O2S Stays at center O2S shorted to voltage
42 Open or short in the ASD relay wiring or connectors.
43 Open or short in number # coil circuit. Indicates that the ignition coil's peak primary circuit current is not achieved with the maximum dwell time.
47 Charging system voltage too low.
An interesting set of problems, which could all be related to the charging system. That is the first one that needs fixed.
Probably just time for a new O2 sensor though.
Fixed your plenum yet?
