Hi, I'm Eric, aka AsianElvis. I used to own a 2005 Speedmaster, and currently have a 2002 America. It recently started running on one cylinder on a trip from Houston, Tx to New Orleans. Broke down at the state line. No spark on left cylinder, and when I switched the primary wires on the coils, I had spark on the left coil, but not on the right. Ignition Module bad?? Wanted to get an expert opinion before laying out over $600 bucks for a new one. I will post this on the tech forum, just wanted to say hello and let you know why I'm here.
