Quick question guys - went over a bump today which somehow managed to disconnect one of the spark plug leads. I ran for about half a mile, with lots of loud bangs from the driver's side exhaust and loss of power, before I could pull over and switch off.
I quickly spotted the problem. But now the (stage 1) exhaust on that side is running almost silent, and there is a strange noise from the engine on full acceleration, almost like a supercharger(!). Or maybe it always made that noise, but the exhaust was drowning it out...
Have I somehow damaged my exhaust by running on one cylinder?
