Having a problem with the old girl!
After a run when up to temp, she runs fine, but when you switch off, and leave. say after 30mins, start the engine and it runs lumpy, if missing a spark?
But i think it cant be a lead or plug, because 1. thier all new and 2. it only happens when the engine is hot?
if it was a lead/plug it would be lumpy when either cold or hot??
so im thinking could it be something electrical thats at fault??
From cold, this morning she started and idled fine!
confused!
help please
