Larry Delor,

Thanks for the speedy reply.
I don't know anything about these engines at the moment but plan on becoming knowledable soon.
I'm guessing that the coil packs will explain the rough running but what about the exhaust leak.
How does one determine which coil pack is bad?
I'm guessing that the exhaust leak is releasing the rotten egg smell of the catilytic converter.
But do all properly operating catilytic converters normally smell of rotten eggs?
