Joseph may be confused by David's comment about the ingnition amplifier
module. NAS distributors have the amplifier mounted inside the
distributor...bad idea. If this goes bad you must replace the
distributor. You can use a later distributor with the external module
or use another distributor..Mallory, Buick, MSD, etc. Some Rover
modules are mounted on the outside of the distributor and some are
mounted on the fender well (inner wing).
Other possible trouble spots: coolant temperature switch, cold start
injector, relay for this injector (I think it has one), or possibly the
extra air valve.
The ECU needs to be done anyway, so I would start there.
All good advice. As a team, Rovernet does a great job.
