Put your car question in the CARS section and you might get some more help you're in Motor homes and caravans section .
Didn't know cars still used coils that year I thought all cars were electronic ignition. Never had a Rover so this is just a thought!
looking back on my old coil ignition cars check all leads low and high tension from the coil through to the distributer, Check the carbon brush in middle of discap is ok and moving, I've even had new one faulty. Someone in the right section might come up with a solution.
