Rolls Royce Silver Shadow Ignition Coil Problems
Coil electrical connectors look corroded
The area around the end of one of the ignition coil packs looks to be rusty and corroded.
High level of hydrocarbons in exhaust
The level of hydrocarbons coming out of the exhaust is above the legal limit. Exhaust hydrocarbon content is generally unburnt fuel and is a sign of poor combustion in the engine.
Engine doesn't start up and/or cuts out when running
The engine doesn't start up very easily and will often not start at all. When it is running it can cut out completely without warning.
Check Engine warning light showing on dashboard
The dashboard warning light showing on this page (or one very similar, sometimes a slightly different shape or colour) has appeared on the dashboard and doesn't go off when the car is running.
Fuel consumption seems above normal range
The fuel gauge seems to be going down quicker than usual, the car is using more fuel when driving in the same way as before.
Engine is rough at idle speed
At idle speed the engine sounds like it's about to stall, it improves when the accelerator is pressed down but when idling in traffic it sounds like it's struggling to run properly.
Engine is misfiring
The engine sounds like it's not running correctly, the engine sounds rough as if it's not running in time.
